## Guide
-1. ci pipeline will be triggered when your comment on pull request matched command.
-2. "**Only triggered by command**". What does that mean?
- * Yes, this ci will be triggered only when your comment on pr matched command.
- * No, this ci will be triggered by every new commit on current pr, comment matched command also trigger ci pipeline.
+ci pipeline will be triggered when your comment on pull request matched command. But we have some task that will be triggered manually.

Note that executing `Swap and Re-evaluate` algorithm is necessary as the `reduced_cost` sometimes is a joint effect of several indexes and it's hard to tell each index's independent contribution to the final `reduced_cost`. For example, assume there is an extremely slow query in input workload and the desired indexes for this query is `a` and `b`. However, the number of allowed recommended indexes for the whole workload is limited and for some reason, `a` ranks top `n` in the final score list while `b` is not. But there are chances that without `b`, `a` can no more optimize that extremely slow query.

+# Foreign Key Design Doc
+
+- Author(s): [crazycs520](https://github.com/crazycs520)
+- Tracking Issue: https://github.com/pingcap/tidb/issues/18209
+
+## Abstract
+
+This proposes an implementation of supporting foreign key constraints.
+
+## DDL Technical Design
+
+### Table Information Changes
+The table's foreign key information will be stored in `model.TableInfo`:
+
+```go
+// TableInfo provides meta data describing a DB table.
+type TableInfo struct {
+ ...
+ ForeignKeys []*FKInfo `json:"fk_info"`
+ // MaxFKIndexID uses to allocate foreign key ID.
+ MaxForeignKeyID int64 `json:"max_fk_id"`
+ ...
+}
+
+// FKInfo provides meta data describing a foreign key constraint.
+type FKInfo struct {
+ ID int64 `json:"id"`
+ Name CIStr `json:"fk_name"`
+ RefSchema CIStr `json:"ref_schema"`
+ RefTable CIStr `json:"ref_table"`
+ RefCols []CIStr `json:"ref_cols"`
+ Cols []CIStr `json:"cols"`
+ OnDelete int `json:"on_delete"`
+ OnUpdate int `json:"on_update"`
+ State SchemaState `json:"state"`
+ Version int `json:"version"`
+}
+```
+
+Struct `FKInfo` uses for the child table to record the referenced parent table. Struct `FKInfo` has existed for a long time, I just added some fields.
+- `Version`: uses to distinguish between old and new versions. The new version value is 1, the old version value is 0.
+
+Why `FKInfo` record the table/schema name instead of table/schema id? Because we may don't know the table/schema id when building `FKInfo`. Here is an example:
+
+```sql
+>set @@foreign_key_checks=0;
+Query OK, 0 rows affected
+>create table t2 (a int key, foreign key fk(a) references t1(id));
+Query OK, 0 rows affected
+>create table t1 (id int key);
+Query OK, 0 rows affected
+>set @@foreign_key_checks=1;
+Query OK, 0 rows affected
+>insert into t2 values (1);
+(1452, 'Cannot add or update a child row: a foreign key constraint fails (`test`.`t2`, CONSTRAINT `t2_ibfk_1` FOREIGN KEY (`a`) REFERENCES `t1` (`id`))')
+```
+
+As you can see, table `t2` refers to table `t1`, and when creating table `t2`, table `t1` still not be created, so we can't know the id of table `t1`.
+

+When building `TableInfo`, an index for the foreign key columns is created automatically if there is no index covering the foreign key columns. Here is an example:
+
+```sql
+mysql> create table t (id int key, a int, foreign key fk(a) references t(id));
+Query OK, 0 rows affected
+mysql> show create table t\G
+***************************[ 1. row ]***************************
+Table | t
+Create Table | CREATE TABLE `t` (
+ `id` int NOT NULL,
+ `a` int DEFAULT NULL,
+ PRIMARY KEY (`id`),
+ KEY `fk` (`a`),
+ CONSTRAINT `t_ibfk_1` FOREIGN KEY (`a`) REFERENCES `t` (`id`)
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci
+1 row in set
+```
+
+As you can see, the index `fk` is created automatically for the foreign key.
+
+#### Validate
+
+Create a table with foreign key, check the following conditions when a DDL job is built and the DDL owner received a DDL job(aka Double-Check):
+
+- whether the user has `REFERENCES` privilege to the foreign key references table.
+- Corresponding columns in the foreign key and the referenced key must have similar data types. The size and sign of fixed precision types such as INTEGER and DECIMAL must be the same. The length of string types need not be the same. For nonbinary (character) string columns, the character set and collation must be the same.
+- Supports foreign key references between one column and another within a table. (A column cannot have a foreign key reference to itself.)
+- Indexes on foreign keys and referenced keys are required, because the foreign key check can be fast and do not require a table scan.
+- Prefixed indexes on foreign key columns are not supported. Consequently, BLOB and TEXT columns cannot be included in a foreign key because indexes on those columns must always include a prefix length.
+- Does not currently support foreign keys for the partition table. This includes both reference and child tables.
+- A foreign key constraint cannot reference any virtual generated columns, but the stored generated columns are fine.
+
+#### Handle In DDL Owner
+
+When the DDL Owner handle create table job, the DDL owner needs to create a new table.
+
+At the same point in time, there may be two versions of the schema in the TiDB cluster, so we can't create a new table and
+update all reference tables in one schema version, since this may break foreign key constraints, such as delete reference table
+without foreign key constraint check in the child table.
+
+```sql
+-- In TiDB-1 and Schema Version is 1
+insert into t_has_foreign_key values (1, 1);
+
+-- In TiDB-0 and Schema Version is 0
+delete from t_reference where id = 1; --Since doesn't know foreign key information in old version, so doesn't do foreign key constrain check.
+```
+
+So, when creating a table with foreign key, we need multi-schema version change:
+
+1. None -> Write Only: Create table with the state is `write-only`.
+2. Write Only -> Public: Update the created table state to `public`.
+
+#### Maintain ReferredFKInfo
+
+Why need to maintain `ReferredFKInfo` in the reference table? When executing `UPDATE`/`DELETE` in the reference table, we need the `ReferredFKInfo` of the reference table to do a foreign key check/cascade.
+
+How to maintain `ReferredFKInfo` in the reference table? When we create table with foreign key, we didn't add `ReferredFKInfo` into the reference table, because the reference table may not have been created yet,
+when `foreign_key_checks` variable value is `OFF`, the user can create a child table before the reference table.
+
+We decided to maintain `ReferredFKInfo` while TiDB loading schema. At first, `infoSchema` will record all table's `ReferredFKInfo`:
+
+```sql
+// ReferredFKInfo provides the referred foreign key in the child table.
+type ReferredFKInfo struct {
+ Cols []CIStr `json:"cols"`
+ ChildSchema CIStr `json:"child_schema"`
+ ChildTable CIStr `json:"child_table"`
+ ChildFKName CIStr `json:"child_fk"`
+}
+```
+
+```go
+type infoSchema struct {
+ // referredForeignKeyMap records all table's ReferredFKInfo.
+ // referredSchemaAndTableName => child SchemaAndTableAndForeignKeyName => *model.ReferredFKInfo
+ referredForeignKeyMap map[SchemaAndTableName]map[SchemaAndTableAndForeignKeyName]*model.ReferredFKInfo
+}
+```
+
+Function `applyTableUpdate` uses `applyDropTable` to drop the old table, uses `applyCreateTable` to create the new table.
+
+In the function `applyDropTable`, we will delete the table's foreign key information from `infoSchema.referredForeignKeyMap`.
+
+In the function `applyCreateTable`, we will add the table's foreign key information into `infoSchema.referredForeignKeyMap` first,
+then get the table's `ReferredFKInfo` by schema name and table name, then store the `ReferredFKInfo` into `TableInfo.ReferredForeignKeys`.
+
+Then `applyTableUpdate` will also need to reload the old/new table's referred table information, also uses `applyDropTable` to drop the old reference table, use `applyCreateTable` to create new reference table.
+
+That's all.
+
+### Alter Table Add Foreign Key
+
+Here is an example:
+
+```sql
+create table t1 (id int key,a int, index(a));
+create table t2 (id int key,a int);
+alter table t2 add foreign key fk(a) references t1(id) ON DELETE CASCADE;
+```
+
+Just like create table, we should validate first, and return an error if the conditions for creating foreign keys are not met, and also need to double-check.
+
+When building `TableInfo`, we need to auto-create an index for foreign key columns if there are no index cover foreign key columns.
+And this divides the problem into two cases:
+- Case-1: No need to create an index automatically, and only add the foreign key constraint.
+- Case-2: Need auto-create index for foreign key
+
+#### Case-1: Only add foreign key constrain
+
+The DDL owner handle adds foreign key constrain step is:
+
+1. None -> Write Only: add foreign key constraint which state is `write-only` into the table.
+2. Write Only -> Write Reorg: check all rows in the table whether has related foreign key exists in the reference table, we can use the following SQL to check:
+
+ ```sql
+ select 1 from t2 where t2.a is not null and t2.a not in (select id from t1) limit 1;
+ ```
+ The expected result is `empty`, otherwise, an error is returned and cancels the DDL job.
+
+3. Write Reorg -> Public: update the foreign key constraint state to `public`.
+
+A problem is, How the DML treat the foreign key on delete/update cascade behaviour in which state is non-public?
+Here is an example:
+
+```sql
+create table t1 (id int key,a int, index(a));
+create table t2 (id int key,a int, index(a));
+insert into t1 values (1,1);
+insert into t2 values (1,1);
+alter table t2 add constraint fk_1 foreign key (a) references t1(id) ON DELETE CASCADE;
+```
+
+The schema change of foreign key `fk_1` is from `None` -> `Write-Only` -> `Write-Reorg` -> `Public`。
+When the foreign key `fk_1` in `Write-Only` state, a DML request has come to be processed:
+
+```sql
+delete from t1 where id = 1;
+```
+
+Then, TiDB shouldn't do cascade delete for foreign key `fk_1` in state `Write-Only`, since the `Add Foreign Key` DDL job maybe
+failed in `Write-Reorg` state and rollback the DDL job. But it is hard to rollback the cascade deleted executed before.
+
+So, when executing DML with `non-public` foreign key, TiDB will do foreign key constraint check instead of foreign key cascade behaviour.
+
+#### Case-2: Auto-create index for foreign key and add foreign key constrain
+
+As TiDB support multi-schema change now, we create an `ActionMultiSchemaChange` job that contains the following 2 sub-ddl job.
+- Add Index DDL job
+- Add Foreign Key Constraint DDL job
+
+When TiDB adds foreign key DDL job meet error, TiDB will rollback the `ActionMultiSchemaChange` job and the 2 sub-ddl job will also be rollback.
+
+### Drop Table
+
+If `foreign_key_checks` is `ON`, then drop the table which has foreign key references will be rejected.
+
+```sql
+> drop table t1;
+(3730, "Cannot drop table 't1' referenced by a foreign key constraint 't2_ibfk_1' on table 't2'.")
+```
+
+### Drop Database
+
+If `foreign_key_checks` is `ON`, then drop the database which has foreign key references by another database will be rejected.
+
+```sql
+> drop database test;
+(3730, "Cannot drop table 't1' referenced by a foreign key constraint 't2_ibfk_1' on table 't2'.")
+```
+
+### Drop Index
+
+Drop index used by the foreign key will be rejected.
+
+```sql
+> set @@foreign_key_checks=0; -- Even disable foreign_key_checks, you still can't drop the index used for foreign key constrain.
+Query OK, 0 rows affected
+> alter table t2 drop index fk;
+(1553, "Cannot drop index 'fk': needed in a foreign key constraint")
+```
+
+### Rename Column
+
+Rename column which has foreign keys or references should also need to update the related child/parent table info.
+
+```sql
+create table t1 (id int key,a int, index(a));
+create table t2 (id int key,a int, foreign key fk(a) references t1(id) ON DELETE CASCADE);
+rename table t1 to t11;
+alter table t11 change column id id1 int;
+show create table t2\G
+***************************[ 1. row ]***************************
+ Table | t2
+Create Table | CREATE TABLE `t2` (
+ `id` int NOT NULL,
+ `a` int DEFAULT NULL,
+ PRIMARY KEY (`id`),
+ KEY `fk` (`a`),
+ CONSTRAINT `t2_ibfk_1` FOREIGN KEY (`a`) REFERENCES `t11` (`id1`) ON DELETE CASCADE
+ ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci
+```
+
+### Truncate Table
+
+A truncate table which has foreign keys or references should also need to update the related child/parent table info.
+
+### Modify Column
+
+Modify column which used by the foreign key will be rejected.
+
+```sql
+> alter table t1 change column id id1 bigint;
+(3780, "Referencing column 'a' and referenced column 'id1' in foreign key constraint 't2_ibfk_1' are incompatible.")
+```
+
+MySQL modify column problem: https://www.percona.com/blog/2019/06/04/ddl-queries-foreign-key-columns-MySQL-pxc/
+
+What if the user really needs to modify column type, such as from `INT` to `BIGINT`. Maybe we can offer a variable such as `alter-foreign-keys-method=auto`,
+then when the user modifies the column type, TiDB will auto-modify the related foreign key column's type. For easy implementation and to reduce risk, maybe only support modifying column type which doesn't need to reorg table row data.
+
+## DML Technical Design
+
+### DML On Child Table
+
+On Child Table Insert Or Update, need to Find FK column value that exist in the reference table:
+
+1. Get reference table info by table name.
+2. Get the related fk index of the reference table.
+3. tiny optimize, check fk column value exists in reference table cache(map[string(index_key)]struct).
+3. Get related row in reference.
+- Construct index key and then use snapshot `Iter` and `Seek` API to scan. If the index is unique and only contain
+ foreign key columns, use the snapshot `Get` API.
+ - `Iter` default scan batch size is 256, need to set 2 to avoid read unnecessary data.
+4. compact column value to make sure exist.
+5. If relate row exist in reference table, also need to add lock in the related row.
+6. put column value into reference fk column value cache.
+
+#### Lock
+
+Let's see an example in MySQL first:
+
+prepare:
+```sql
+create table t1 (id int key,a int, b int, unique index(a, b, id));
+create table t2 (id int key,a int, b int, index (a,b,id), foreign key fk(a, b) references t1(a, b));
+insert into t1 values (-1, 1, 1);
+```
+
+Then, execute the following SQL in 2 sessions:
+
+| Session 1 | Session 2 |
+| -------------------------------- | ------------------------------------------- |
+| Begin; | |
+| insert into t2 values (1, 1, 1); | |
+| | delete from t1; -- Blocked by wait lock |
+| Commit | |
+| | ERROR: Cannot delete or update a parent row |
+
+So we need to add lock in the reference table when insert/update child table.
+
+##### In Pessimistic Transaction
+
+When TiDB add pessimistic locks, if related row exists in the reference table, also needs to add lock in the related row.
+
+##### In Optimistic Transaction
+
+Just like `SELECT FOR UPDATE` statement, need to use `doLockKeys` to lock the related row in the reference table.
+
+##### Issue
+
+TiDB currently only support `lock for update`(aka write-lock, such as `select for update`), and doesn't support `lock for share`(aka read-lock, such as `select for share`).
+
+So far we have to add `lock for update` in the reference table when insert/update child table, then the performance will be poor. After TiDB support `lock for share`, we should use `lock for share` instead.
+
+#### DML Load data
+
+Load data should also do foreign key check, but report a warning instead error:
+
+```sql
+create table t1 (id int key,a int, index(a));
+create table t2 (id int key,a int, foreign key fk(a) references t1(id) ON DELETE CASCADE);
+
+test> load data local infile 'data.csv' into table t2 FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n';
+Query OK, 0 rows affected
+test> show warnings;
++---------+------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------+
+| Level | Code | Message |
++---------+------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------+
+| Warning | 1452 | Cannot add or update a child row: a foreign key constraint fails (`test`.`t2`, CONSTRAINT `t2_ibfk_1` FOREIGN KEY (`a`) REFERENCES `t1` (`id`) ON DELETE CASCADE) |
+| Warning | 1452 | Cannot add or update a child row: a foreign key constraint fails (`test`.`t2`, CONSTRAINT `t2_ibfk_1` FOREIGN KEY (`a`) REFERENCES `t1` (`id`) ON DELETE CASCADE) |
++---------+------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------+
+```
+
+`data.csv` is:
+```
+1,1
+2,2
+```
+
+### DML On reference Table
+
+On reference Table Delete Or Update:
+
+1. modify related child table row by referential action:
+- `CASCADE`: update/delete related child table row.
+- `SET NULL`: set related child row's foreign key columns value to NULL.
+- `RESTRICT`, `NO ACTION`: If related row exist in child table, reject update/delete the reference table.
+- `SET DEFAULT`: just like `RESTRICT`.
+
+modify related child table rows by the following step:
+1. get child table info by name(in reference table info).
+2. get the child table fk index's column info.
+3. build update executor to update child table rows.
+
+### Issue need to be discussed
+
+#### Affect Row
+
+related article: https://www.percona.com/blog/hidden-cost-of-foreign-key-constraints-in-MySQL/
+
+Here is a MySQL example:
+
+prepare:
+```sql
+create table t1 (id int key,a int, index(a));
+create table t2 (id int key,a int, foreign key fk(a) references t1(id) ON DELETE CASCADE);
+insert into t1 values (1, 1);
+insert into t2 values (1, 1);
+```
+
+Then delete on reference table:
+```sql
+> delete from t1 where id=1;
+Query OK, 1 row affected
+```
+
+As you can see, in the query result, the affected row is 1, but actually should be 2, since the related row in t2 is also been deleted.
+
+This is a MySQL behaviour, We can be compatible with it.
+
+#### DML Execution plan
+
+Here is a MySQL example:
+
+prepare:
+```sql
+create table t1 (id int key,a int, index(a));
+create table t2 (id int key,a int, foreign key fk(a) references t1(id) ON DELETE CASCADE);
+insert into t1 values (1, 1);
+insert into t2 values (1, 1);
+```
+
+```sql
+> explain delete from t1 where id = 1;
++----+-------------+-------+------------+-------+---------------+---------+---------+-------+------+----------+-------------+
+| id | select_type | table | partitions | type | possible_keys | key | key_len | ref | rows | filtered | Extra |
++----+-------------+-------+------------+-------+---------------+---------+---------+-------+------+----------+-------------+
+| 1 | DELETE | t1 | | range | PRIMARY | PRIMARY | 4 | const | 1 | 100.0 | Using where |
++----+-------------+-------+------------+-------+---------------+---------+---------+-------+------+----------+-------------+
+```
+
+From the plan, you can't see any information about the foreign key constraint which needs to delete the related row in child table `t2`.
+
+I think this is a MySQL issue, should we make TiDB plan better, at least when we meet some slow query, we can know maybe it is caused by modify related rows in the child table.
+
+Here is an example plan with foreign key:
+
+```sql
+> explain delete from t1 where id = 1;
++-------------------------+---------+------+---------------+-----------------------------------+
+| id | estRows | task | access object | operator info |
++-------------------------+---------+------+---------------+-----------------------------------+
+| Delete_2 | N/A | root | | N/A |
+| ├─Point_Get_1 | 1.00 | root | table:t1 | handle:1 |
+| └─Foreign_Key_Cascade_3 | 0.00 | root | table:t2 | foreign_key:fk, on_delete:CASCADE |
++-------------------------+---------+------+---------------+-----------------------------------+
+```
+
+And the `explain analyze` will show the foreign key cascade child plan:
+
+```sql
+> explain analyze delete from t1 where id = 1;
++-------------------------+---------+---------+------+---------------+----------------------------------------------------------+-----------------------------------+-----------+------+
+| id | estRows | actRows | task | access object | execution info | operator info | memory | disk |
++-------------------------+---------+---------+------+---------------+----------------------------------------------------------+-----------------------------------+-----------+------+

+
+## Compatibility
+
+Since the old version TiDB already support foreign key syntax, but doesn't support it, after upgrade TiDB to latest version, the foreign key created before won't take effect. Only foreign keys created in the new version actually take effect.
+
+You can use `SHOW CREATE TABLE` to see whethere a foreign key is take effect, the old version foreign key will have a comment `/* FOREIGN KEY INVALID */` to indicate it is invalid, the new version foreign key doesn't have this comment.
+
+```sql
+> show create table t2\G
+ ***************************[ 1. row ]***************************
+ Table | t2
+Create Table | CREATE TABLE `t2` (
+ `id` int(11) NOT NULL,
+ PRIMARY KEY (`id`) /*T![clustered_index] CLUSTERED */,
+ CONSTRAINT `fk` FOREIGN KEY (`id`) REFERENCES `test`.`t1` (`id`) ON DELETE CASCADE ON UPDATE CASCADE /* FOREIGN KEY INVALID */
+ ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin
+```
+
+## Impact
+
+### Impact of data replication
+
+#### TiCDC
+
+When syncing table data to downstream TiDB, TiCDC should `set @@foreign_key_checks=0` in downstream TiDB.
+
+#### DM
+
+When doing full synchronization, DM should `set @@foreign_key_checks=0` in downstream TiDB.
+
+When doing incremental synchronization, DM should set `foreign_key_checks` session variable according to MySQL binlog.
+
+#### BR
+
+When restore data into TiDB, BR should `set @@foreign_key_checks=0` in TiDB.
+
+## Test Case
+
+Cascade modification test case:
+
+```sql
+drop table if exists t3,t2,t1;
+create table t1 (id int key,a int, index(a));
+create table t2 (id int key,a int, foreign key fk(a) references t1(id) ON DELETE CASCADE);
+create table t3 (id int key,a int, foreign key fk(a) references t2(id) ON DELETE CASCADE);
+insert into t1 values (1,1);
+insert into t2 values (2,1);
+insert into t3 values (3,2);
+delete from t1 where id = 1; -- both t1, t2, t3 rows are deleted.
+```
+
+Following is a MySQL test case about `SET DEFAULT`, as you can see, MySQL actualy doesn't support `SET DEFAULT`, the behaviour is just like `RESTRICT`
+
+```sql
+MySQL>create table t1 (a int,b int, index(a,b)) ;
+Query OK, 0 rows affected
+Time: 0.022s
+MySQL>create table t (a int, b int, foreign key fk_a(a) references test.t1(a) ON DELETE SET DEFAULT);
+Query OK, 0 rows affected
+Time: 0.019s
+MySQL>insert into t1 values (1,1);
+Query OK, 1 row affected
+Time: 0.003s
+MySQL>insert into t values (1,1);
+Query OK, 1 row affected
+Time: 0.006s

+(1451, 'Cannot delete or update a parent row: a foreign key constraint fails (`test`.`t`, CONSTRAINT `t_ibfk_1` FOREIGN KEY (`a`) REFERENCES `t1` (`a`))')
+MySQL>select version();
++-----------+
+| version() |
++-----------+
+| 8.0.29 |
++-----------+
+```
+
+### Self-Referencing Tables
+
+For example, table `employee` has a column `manager_id` references to `employee.id`.
+
+```sql
+create table employee (id int key,manager_id int, foreign key fk(manager_id) references employee(id) ON DELETE CASCADE);
+insert into employee values (1,1);
+insert into employee values (2,1);
+
+test> delete from employee where id=1;
+Query OK, 1 row affected
+test> select * from employee;
++----+---+
+| id | a |
++----+---+
+0 rows in set
+```
+
+A case of self-reference and cyclical dependencies:
+
+```sql
+test> create table t (id int key,a int, foreign key fk_a(a) references t(id) ON DELETE CASCADE, foreign key fk_id(id) references t(a) ON DELETE CASCADE);
+Query OK, 0 rows affected
+Time: 0.045s
+test> insert into t values (1,1);
+(1452, 'Cannot add or update a child row: a foreign key constraint fails (`test`.`t`, CONSTRAINT `t_ibfk_2` FOREIGN KEY (`id`) REFERENCES `t` (`a`) ON DELETE CASCADE)')

+# Proposal: Global Memory Control
+
+* Authors: [wshwsh12](https://github.com/wshwsh12), [Xuhuaiyu](https://github.com/Xuhuaiyu)
+* Tracking issue: [#37816](https://github.com/pingcap/tidb/issues/37816)
+
+## Abstract
+
+This proposes a design of how to control global memory of TiDB instance.
+
+## Background
+
+Currently, TiDB has a query-level memory control strategy `mem-quota-query`, which triggers Cancel when the memory usage of a single SQL exceeds `mem-quota-query`. However, there is currently no global memory control strategy.
+
+When TiDB has multiple SQLs whose memory usage does not exceed `mem-quota-query` or memory tracking inaccurate, it will lead to high memory usage or even OOM.
+
+Therefore, we need an observer to check whether the memory usage of the current system is normal. When there are some problems, try to control TiDB's memory no longer continue to grow, to reduce the risk of process crashes.
+
+## Goal
+
+- Control the TiDB execution memory within the system variable `tidb_server_memory_limit`.
+
+## Design
+
+New system variables:
+- `tidb_server_memory_limit`: TiDB maintains the overall memory usage within `tidb_server_memory_limit`
+- `tidb_server_memory_gc_trigger`: When TiDB memory usage reaches a certain percentage of `tidb_server_memory_limit`, try to take the initiative to trigger golang GC to release memory
+- `tidb_server_memory_limit_sess_min_size`: The minimum memory of a session that can be killed by TiDB
+
+We need to implement the following three functions to control the memory usage of TiDB:
+1. Kill the SQL with the most memory usage in the current system, when `HeapInuse` is larger than `tidb_server_memory_limit`.
+2. Take the initiative to trigger `runtime.GC()`, when `HeapInuse` is large than `tidb_server_memory_limit`*`tidb_server_memory_limit_gc_trigger`.
+3. Introduce some memory tables to observe the memory status of the current system.
+
+### Kill the SQL with the max memory usage
+
+New variables:
+
+1. Global variable `MemUsageTop1Tracker atomic.Pointer[Tracker]`: Indicates the Tracker with the largest memory usage.
+2. The flag `NeedKill atomic.Bool` in the structure `Tracker`: Indicates whether the SQL for the current Tracker needs to be Killed.
+3. `SessionID int64` in Structure Tracker: Indicates the Session ID corresponding to the current Tracker.
+
+Implements:
+
+#### How to get the current TiDB memory usage Top 1
+When `Tracker.Consume()` calling, check the following logic. If all are satisfied, update the `MemUsageTop1Tracker`.
+1. Is it a Session-level Tracker?
+2. Whether the flag `NeedKill` is false, to avoid cancel the current SQL twice
+3. Whether the memory usage exceeds the threshold `tidb_server_memory_limit_sess_min_size`(default 128MB, can be dynamically adjusted), can be candidate of the `MemUsageTop1Tracker`
+4. Is the memory usage of the current Tracker greater than the current `MemUsageTop1Tracker`
+
+#### How to Cancel the current top 1 memory usage and recycle memory in time
+1. Create a goroutine that calls Golang's `ReadMemStat` interface in a 100 ms cycle. (Get the memory usage of the current TiDB instance)
+2. If the `heapInuse` of the current instance is greater than `tidb_server_memory_limit`, set `MemUsageTop1Tracker`'s `NeedKill` flag. (Sends a Kill signal)
+3. When the SQL call to `Tracker.Consume()`, check its own `NeedKill` flag. If it is true, trigger Panic and exit. (terminates the execution of SQL)
+4. Get the `SessionID` from the tracker and continuously query its status, waiting for it to complete exited. When SQL successfully exited, explicitly trigger Golang GC to release memory. (Wait for SQL exited completely and release memory)
+
+### Take the initiative to trigger GC
+
+The inspiration for this design comes from uber-go-gc-tuner:
+1. Use the Go1.19 `SetMemoryLimit` feature to set the soft limit to `tidb_server_memory_limit` * `tidb_server_memory_limit_gc_trigger` to ensure that GC can be triggered when reaching the certain threshold.
+2. After each GC, check whether this GC is caused by memory limit. If it is caused by this, temporarily set memory limit to infinite, and then set it back to the specified threshold after 1 minute. In this way, the problem of frequent GC caused by `heapInUse` being larger than the soft limit can be avoided.
+
+### Introduce some memory tables
+
+Introduce `performance_schema.memory_usage` and `performance_schema.memory_usage_ops_history` to display the current system memory usage and historical operations.
+This can be implemented by maintaining a set of global data, and reading and outputting directly from the global data when querying.

+# Proposal: Flashback To Timestamp
+- Author(s): [Defined2014](https://github.com/Defined2014) and [JmPotato](https://github.com/JmPotato)
+- Last updated: 2022-12-19
+- Tracking Issues: https://github.com/pingcap/tidb/issues/37197 and https://github.com/tikv/tikv/issues/13303
+
+## Abstract
+
+This proposal aims to support `Flashback To Timestamp` and describe what `Flashback To Timestamp` should look like and how to implement it.
+
+## Background
+
+Some users want to `Flashback table/database/cluster` to the specified timestamp when there is a problem with the data like deleted some important keys, updated wrong values etc.
+
+TiDB uses MVCC to store key-values, which means it can easily get historical data at any timestamp. Based on this feature, TiDB already supports `Flashback To Timestamp`, for example, users can read historical data and update it through Snapshot Read which is not only inelegant, but also inefficient.
+
+Therefore, we propose to use a series of new SQL syntaxes to support this feature, and push down the read-write operations to storage side.
+
+## Detailed Design
+
+### Implementation Overview
+
+In TiKV, a multi-version concurrency control (MVCC) mechanism is introduced to avoid the overhead of introducing locks when data is updated concurrently. Under this mechanism, when TiDB modified data, it doesn't directly operate on the original value, but writes a data with the latest timestamp to cover it. The GC Worker in the background of TiDB will periodically update `tikv_gc_safe_point` and delete the version older than this point. `Flashback To Timestamp` is developmented based on this feature of TiKV. In order to improve execution efficiency and reduce data transmission overhead, TiKV has added two RPC interfaces called `PrepareFlashbackToVersion` and `FlashbackToVersion`. The protobuf related change shown below:
+
+```protobuf
+// Preparing the flashback for a region/key range will "lock" the region
+// so that there is no any read, write or schedule operation could be proposed before
+// the actual flashback operation.
+message PrepareFlashbackToVersionRequest {
+ Context context = 1;
+ bytes start_key = 2;
+ bytes end_key = 3;
+}
+
+message PrepareFlashbackToVersionResponse {
+ errorpb.Error region_error = 1;
+ string error = 2;
+}
+
+// Flashback the region to a specific point with the given `version`, please
+// make sure the region is "locked" by `PrepareFlashbackToVersionRequest` first,
+// otherwise this request will fail.
+message FlashbackToVersionRequest {
+ Context context = 1;
+ // The TS version which the data should flashback to.
+ uint64 version = 2;
+ bytes start_key = 3;
+ bytes end_key = 4;
+ // The `start_ts`` and `commit_ts` which the newly written MVCC version will use.
+ uint64 start_ts = 5;
+ uint64 commit_ts = 6;
+}
+
+message FlashbackToVersionResponse {
+ errorpb.Error region_error = 1;
+ string error = 2;
+}
+```
+
+Then a `Flashback To Timestamp` DDL job can be simply divided into the following steps
+
+* Save values of some global variables and PD schedule. Those values will be changed during `Flashback`.
+
+* Pre-checks. After all checks are passed, TiDB will disable GC and closed PD schedule for the cluster. The specific checks are as follows:
+ * The FlashbackTS is after `tikv_gc_safe_point`.
+ * The FlashbackTS is before the minimal store resolved timestamp.
+ * No DDL job was executing at FlashbackTS.
+ * No running related DDL jobs.
+
+* TiDB get flashback key ranges and splits them into separate regions to avoid locking unrelated key ranges. Then TiDB send `PrepareFlashbackToVersion` RPC requests to lock regions in TiKV. Once locked, no more read, write and scheduling operations are allowed for those regions.
+
+* After locked all relevant key ranges, the DDL owner will update schema version and synchronize it to other TiDBs. When other TiDB applies the `SchemaDiff` of type `Flashback To Timestamp`, it will disconnect all relevant links.
+
+* Send `FlashbackToVersion` RPC requests to all relevant key ranges with same `commit_ts`. Each region handles its own flashback progress independently.
+ * Read the old MVCC data and write it again with the given `commit_ts` to pretend it's a new transaction commit.
+ * Release the Raft proposing lock and resume the lease read.
+
+* TiDB checks whether all the requests returned successfully, and retries those failed requests with the same `commit_ts`. After all requests finished, the DDL owner update the schema version with new type named `ReloadSchemaMap`, so that all TiDB servers regenerate the schema map from TiKV.
+
+* After `Flashback To Timestamp` is finished, TiDB will restore all changed global variables and restart PD schedule. At the same time, notify `Stats Handle` to reload statistics from TiKV.
+
+### New Syntax Overview
+
+TiDB will support 3 new syntaxes as follows.
+
+1. Flashback whole cluster except some system tables to the specified timestamp.
+
+```sql
+FLASHBACK CLUSTER TO TIMESTAMP '2022-07-05 08:00:00';
+```
+
+2. Flashback some databases to the specified timestamp.
+
+```sql
+FLASHBACK DATABASE [db] TO TIMESTAMP '2022-07-05 08:00:00';
+```
+
+3. Flashback some tables to the specified timestamp.
+
+```sql
+FLASHBACK TABLE [table1], [table2] TO TIMESTAMP '2022-08-10 08:00:00';
+```
+
+### Limitations and future Work
+
+1. Compare with the other DDL jobs, `Flashback To Timestamp` job cannot be rollbacked after some regions failure and also needs to resend rpc to all regions when ddl owner crashed. In the future, we will improve those two issues with a new TiKV interface and new distributed processing ddl framework.
+
+### Alternative Solutions
+
+1. Read historical data via `As of timestamp` clause and write back with the lastest timestamp. But it's much slower than `Flashback To Timestamp`, the data needs to be read to TiDB first then written back to TiKV.
+
+2. Use `Reset To Version` interface to delete all historical version. After this operation, the user can't find the deleted version any more and this interface is incompatible with snapshot read.

+## Introduction
+
+Support ALTER TABLE t REORGANIZE PARTITION p1,p2 INTO (partition pNew1 values...)
+
+## Motivation or Background
+
+TiDB is currently lacking the support of changing the partitions of a partitioned table, it only supports adding and dropping LIST/RANGE partitions.
+Supporting REORGANIZE PARTITIONs will allow RANGE partitioned tables to have a MAXVALUE partition to catch all values and split it into new ranges. Similar with LIST partitions where one can split or merge different partitions.
+
+When this is implemented, it will also allow future PRs transforming a non-partitioned table into a partitioned table as well as remove partitioning and make a partitioned table a normal non-partitioned table, as well as COALESCE PARTITION and ADD PARTITION for HASH partitioned tables, which is different ALTER statements but can use the same implementation as REORGANIZE PARTITION
+
+The operation should be online, and must handle multiple partitions as well as large data sets.
+
+Possible usage scenarios:
+- Full table copy
+ - merging all partitions to a single table (ALTER TABLE t REMOVE PARTITIONING)
+ - splitting data from many to many partitions, like change the number of HASH partitions
+ - splitting a table to many partitions (ALTER TABLE t PARTITION BY ...)
+- Partial table copy (not full table/all partitions)
+ - split one or more partitions
+ - merge two or more partitions
+
+These different use cases can have different optimizations, but the generic form must still be solved:
+- N partitions, where each partition has M indexes
+
+First implementation should be based on the merge-txn (row-by-row batch read, update record key with new Physical Table ID, write) transactional batches and then create the indexes in batches index by index, partition by partition.
+Later we can implement the ingest (lightning way) optimization, since DDL module are on the way of evolution to do reorg tasks more efficiency.
+
+## Detailed Design
+
+There are two parts of the design:
+- Schema change states throughout the operation
+- Reorganization implementation, which will be handled in the StateWriteReorganization state.
+
+Where the schema change states will clarify which different steps that will be done in which schema state transitions.
+
+### Schema change states for REORGANIZE PARTITION
+
+Since this operation will:
+- create new partitions
+- copy data from dropped partitions to new partitions and create their indexes
+- change the partition definitions
+- drop existing partitions
+
+It will use all these schema change stages:
+
+ // StateNone means this schema element is absent and can't be used.
+ StateNone SchemaState = iota
+ - Check if the table structure after the ALTER is valid
+ - Use the generate physical table ids to each new partition (that was generated already by the client sending the ALTER command).
+ - Update the meta data with the new partitions (AddingDefinitions) and which partitions to be dropped (DroppingDefinitions), so that new transactions can double write.
+ - Set placement rules
+ - Set TiFlash Replicas
+ - Set legacy Bundles (non-sql placement)
+ - Set the state to StateDeleteOnly
+
+ // StateDeleteOnly means we can only delete items for this schema element (the new partition).
+ StateDeleteOnly
+ - Set the state to StateWriteOnly
+
+ // StateWriteOnly means we can use any write operation on this schema element,
+ // but outer can't read the changed data.
+ StateWriteOnly
+ - Set the state to StateWriteReorganization
+
+ // StateWriteReorganization means we are re-organizing whole data after write only state.
+ StateWriteReorganization
+ - Copy the data from the partitions to be dropped (one at a time) and insert it into the new partitions. This needs a new backfillWorker implementation.
+ - Recreate the indexes one by one for the new partitions (one partition at a time) (create an element for each index and reuse the addIndexWorker). (Note: this can be optimized in the futute, either with the new fast add index implementation, based on lightning. Or by either writing the index entries at the same time as the records, in the previous step, or if the partitioning columns are included in the index or handle)
+ - Replace the old partitions with the new partitions in the metadata when the data copying is done
+ - Set the state to StateDeleteReorganization
+
+ // StateDeleteReorganization means we are re-organizing whole data after delete only state.
+ StateDeleteReorganization - we are using this state in a slightly different way than the comment above says.
+ This state is needed since we cannot directly move from StateWriteReorganization to StatePublic.
+ Imagine that the StateWriteReorganization is complete and we are updating the schema version, then if a transaction seeing the new schema version is writing to the new partitions, then those changes needs to be written to the old partitions as well, so new transactions in other nodes using the older schema version can still see the changes.
+ - Remove the notion of new partitions (AddingDefinitions) and which partitions to be dropped (DroppingDefinitions) and double writing will stop when it goes to StatePublic.
+ - Register the range delete of the old partition data (in finishJob / deleteRange).
+ - Set the state to StatePublic
+
+ // StatePublic means this schema element is ok for all write and read operations.
+ StatePublic
+ - Table structure is now complete and the table is ready to use with its new partitioning scheme
+ - Note that there is a background job for the GCWorker to do in its deleteRange function.
+
+During the reorganization happens in the background the normal write path needs to check if there are any new partitions in the metadata and also check if the updated/deleted/inserted row would match a new partition, and if so, also do the same operation in the new partition, just like during adding index or modify column operations currently does. (To be implemented in `(*partitionedTable) AddRecord/UpdateRecord/RemoveRecord`)
+
+Example of why an extra state between StateWriteReorganize and StatePublic is needed:
+
+```sql
+-- table:
+CREATE TABLE t (a int) PARTITION BY LIST (a) (PARTITION p0 VALUES IN (1,2,3,4,5), PARTITION p1 VALUES IN (6,7,8,9,10));
+-- during alter operation:
+ALTER TABLE t REORGANIZE PARTITION p0 INTO (PARTITION p0a VALUES IN (1,2,3), PARTITION p0b VALUES IN (4,5));
+```
+
+Partition within parentheses `(p0a [1] p0b [0])` is hidden or to be deleted by GC/DeleteRange. Values in the brackets after the partition `p0a [2]`.
+
+If we go directly from StateWriteReorganize to StatePublic, then clients one schema version behind will not see changes to the new partitions:
+
+| Data (TiKV/Unistore) | TiDB client 1 | TiDB client 2 |
+| --------------------------------------- | ------------------------------------ | ------------------------------------------------------------ |
+| p0 [] p1 [] StateWriteReorganize | | |
+| p0 [] p1 [] (p0a [] p0b []) | | |
+| (p0 []) p1 [] p0a [] p0b [] StatePublic | | |
+| (p0 []) p1 [] p0a [2] p0b [] | StatePublic INSERT INTO T VALUES (2) | |
+| (p0 []) p1 [] p0a [2] p0b [] | | StateWriteReorganize SELECT * FROM t => [] (only sees p0,p1) |
+
+
+But if we add a state between StateWriteReorganize and StatePublic and double write to the old partitions during that state it works:
+
+
+| Data (TiKV/Unistore) | TiDB client 1 | TiDB client 2 |
+| ------------------------------------------------- | ---------------------------------------------- | -------------------------------------------------------------------- |
+| p0 [] p1 [] (p0a [] p0b []) StateWriteReorganize | | |
+| (p0 []) p1 [] p0a [] p0b [] StateDeleteReorganize | | |
+| (p0 [2]) p1 [] p0a [2] p0b [] | StateDeleteReorganize INSERT INTO T VALUES (2) | |
+| (p0 [2]) p1 [] p0a [2] p0b [] | | StateWriteReorganize SELECT * FROM t => [2] (only sees p0,p1) |
+| (p0 [2]) p1 [] p0a [2] p0b [] StatePublic | | |
+| (p0 [2]) p1 [] p0a [2] p0b [4] | StatePublic INSERT INTO T VALUES (4) | |
+| (p0 [2]) p1 [] p0a [2] p0b [4] | | StateDeleteReorganize SELECT * FROM t => [2,4] (sees p0a,p0b,p1) |
+
+
+### Error handling
+
+If any non-retryable error occurs, we will call onDropTablePartition and adjust the logic in that function to also handle the roll back of reorganize partition, in a similar way as it does with model.ActionAddTablePartition.
+
+### Notes
+
+Note that parser support already exists.
+There should be no issues with upgrading, and downgrade will not be supported during the DDL.
+
+Notes:
+- statistics should be removed from the old partitions.
+- statistics will not be generated for the new partitions (future optimization possible, to get statistics during the data copying?)
+- the global statistics (table level) will remain the same, since the data has not changed.
+- this DDL will be online, while MySQL is blocking on MDL.
+
+## Test Design
+
+Re-use tests from other DDLs like Modify column, but adjust them for Reorganize partition.
+A separate test plan will be created and a test report will be written and signed off when the tests are completed.
+
+### Benchmark Tests
+
+Correctness and functionality is higher priority than performance.
+
+## Impacts & Risks
+
+Impacts:
+- better usability of partitioned tables
+- online alter in TiDB, where MySQL is blocking
+- all affected data needs to be read (CPU/IO/Network load on TiDB/PD/TiKV), even multiple times in case of indexes.
+- all data needs to be writted (duplicated, both row-data and indexes), including transaction logs (more disk space on TiKV, CPU/IO/Network load on TiDB/PD/TiKV and TiFlash if configured on the table).
+
+Risks:
+- introduction of bugs
+ - in the DDL code
+ - in the write path (double writing the changes for transactions running during the DDL)
+- out of disk space
+- out of memory
+- general resource usage, resulting in lower performance of the cluster

+# View Hint Design Doc
+- Author: Reminiscent
+- Tracking Issue: https://github.com/pingcap/tidb/issues/37887
+
+## Background
+Hints that specify a table generally refer to tables in the DELETE, SELECT, or UPDATE query block in which the hint occurs, not to tables inside any views referenced by the statement. So we introduce the view hint to specify the table in view instead of embedding the hint in the view.
+
+In Oracle, there are three ways to use the global hint. (Node: the `{}` part is only used for explanation)
+```SQL
+CREATE OR REPLACE VIEW v AS
+SELECT {SEL$2} * from e1 join (select {SEL$3} * from e3) e2 on e1.a = e2.a;
+
+SELECT {SEL$1} * FROM v;
+
+A. SELECT /*+ INDEX(v.e2.e3 idx) */ * FROM v; // /*+ INDEX(@SEL$1 v.e2.e3 idx) */
+
+B. SELECT /*+ INDEX(@SEL$2 e2.e3 idx) */ * FROM v;
+
+C. SELECT /*+ INDEX(@SEL$3 e3 idx) */ * FROM v;
+```
+
+Compared with TiDB, Oracle has two differences:
+1. Oracle can use `alias.table` to represent in subquery, such as e2.e3. Besides, TiDB can use `db.table` to represent a table.
+2. The count for query block number treats view like a subquery, which means the select parts in view are counted.
+
+Based on the difference, there are some reasons why TiDB can not just use the grammar from Oracle:
+1. Compatibility
+ 1. Grammar.
+ 1. We can not use the `alias.table` to represent in subquery, such as e2.e3.
+ 2. We can use `db.table` to represent a table. So if we want to use the `view.table` to represent a table in view, we should change the grammar or it will conflict with db.table.
+ 2. The count for the query block.
+ 1. Previously, the query block in view would not be counted. But now, if we take the view into consideration, it will change the origin count. For example, in the following part. The count of the query block for the `select a from t1` will be changed from `@SEL_2` to `@SEL_3`. So if we use the query block related hints for this part, it will be invalid or represent the content in the view.
+
+```SQL
+CREATE OR REPLACE VIEW v AS
+SELECT {SEL$2} * FROM t;
+
+SELECT {SEL$1} * FROM v JOIN (select {SEL$3} a from t1) t2 on v.a = t2.a;
+```
+
+So based on the above reasons, we should introduce another way to let hint take effect in the view.
+
+## Detailed Design
+### How does origin hint framework work?
+1. Parser: parse the sql text and get the basic information about the hint. Handle hint syntax error in this phase.
+2. Optimizer:
+ 1. Divide and mark the query block. Besides, group the hints in the same query blocks.
+ 2. In the plan builder phase, when we try to build select. We will handle the hints in the current query block. Including doing some simple checks and building the hints structure which can be used by planner.
+ 3. When we build some logical operators, we will use the hints which belongs to the current query block. And tt will use the table in hint to match the table in the plan node. For example, when we build the `DataSource` operator, it will generate the possible access path based on the index hints. When we build the `Aggregation` operator, it will set the aggregation algorithm based on the agg hints. And for the `Join` operator, it will store the hint in the join node and use the hint information in the physical optimization phase. The warning about which table is not used in the hint will be recorded in this phase.
+ 4. Use the hint information in the physical optimization phase to determine which physical algorithm should be used. And if the hint can not take effect, it will report warning. For example, if the join can not use the index join, but we set the index join hint in the sql text. It will report related warnings.
+
+### View Hint Design
+Based on the goal and current infrastructure for hint. I extend the current usage of the qb_name hint to a bigger scope to support the view hint.
+
+An example to show the usage of the current `qb_name` hint.
+```SQL
+select /*+ stream_agg(@qb) merge_join(t1@qb)*/ * from (select /*+ qb_name(qb) */ count(*) from t1 join t2 on t1.a = t2.a) tt;
+```
+1. First, we define the name for some query blocks.
+2. Then we can use the query block name to represent the query block.
+
+Based on the meaning of `qb_name` hint now, we can expand it to support the view. The basic idea is the same here. We define the query block name in the view first. And then we can use the query block name to represent the contents in the view. Now the grammar is expanded from
+`qb_name(name)` in the query block which you want to rename
+To
+`qb_name(name, viewName@queryBlockNum . {viewName}@queryBlockNum . ...)` in the first query block to represent any query block. Besides, we will reset the count for query block in every view. It means, for every view, it always counts from 1 and it will not effect the outer part.
+For example:
+```SQL
+create table t(a int, b int);
+create table t1(a int, b int);
+create table t2(a int, b int);
+
+create view v as select {@SEL_1}{5} t.a, t.b from t join (select {@SEL_2}{6} t1.a from t1 join t2 on t1.b=t2.b) tt on t.a = tt.a;
+
+create view v1 as select {@SEL_1}{3} t.a, t.b from t join (select {@SEL_2}{4} from t1 join v on t1.b=v.b) tt on t.a = tt.a;
+
+create view v2 as select {@SEL_1}{1} t.a, t.b from t join (select {@SEL_2}{2} t1.a from t1 join v1 join v3 on t1.b=v1.b) tt on t.a = tt.a;
+
+select {@SEL_1} * from v2;
+
+/* We can use the following part to represent the {1} - {6} */
+1: qb_name(v2_sel1, v2@sel_1 . @sel_1)
+2: qb_name(v2_sel2, v2@sel_1 . @sel_2)
+3: qb_name(v1_sel1, v2@sel_1 . v1@sel_2 . @sel_1)
+4: qb_name(v1_sel2, v2@sel_1 . v1@sel_2 . @sel_2)
+5: qb_name(v_sel1, v2@sel_1 . v1@sel_2 . v@sel_2 . @sel_1)
+6: qb_name(v_sel2, v2@sel_1 . v1@sel_2 . v@sel_2 . @sel_2)
+```
+Take the previous as example:
+```SQL
+CREATE OR REPLACE VIEW v AS
+SELECT * from e1 join (select count(*) from e3) e2 on e1.a = e2.a;
+
+
+/* In Oracle */
+A1. SELECT /*+ INDEX(v.e2.e3 idx) */ * FROM v;
+
+A2. SELECT /*+ INDEX(@SEL$1 v.e2.e3 idx) */ * FROM v;
+
+B. SELECT /*+ INDEX(@SEL$2 e2.e3 idx) */ * FROM v;
+
+C. SELECT /*+ INDEX(@SEL$3 e3 idx) */ * FROM v;
+
+/* In TiDB */
+SELECT /*+ qb_name(viewSub, v@sel_1 . @sel_2) use_index(e3@viewSub, idx) hash_agg(viewSub) */ * FROM v;
+```
+
+### Implementation
+Parser part is easy to implement. Just to expand the origin `qb_name` hint grammar. The only problem maybe is how to express the nested view(use dot or blank or something else).
+
+For the planner part:
+1. At the beginning of the optimization, we should handle the query block name hint for view and the other method hints for view. And group these hints based on the query block name.
+2. When we try to build the data source from the view, we have to traverse all of the query blocks for views. Check whether the view name in hint can match the data source or not. If there are some hints that can match, we pass it to the `buildDataSourceFromView`.
+3. When we try to build the view plan, we first handle the hints which are passed by the caller. Distinguish which hints belong to the current view and which belongs to the nested view. If the hint belongs to the current view, we transform the hint to the normal hint. If the hints belong to the nested view. Then we will do the same thing, like step2.
+
+Besides the planner part, we need support to show the query block for a sql to increase usability. The user can copy the result and use it in hint directly.
+
+### Support Scope
+1. We can support almost all physical algorithm's hints. Like join hints/ agg hints/ index etc.
+2. Do not support the leading hints which may be across the view. But we can support the leading hint in the same view.
+
+### Pros and Cons
+Pros:
+1. No compatibility problems. Just expand the usage of the existing hint.
+2. It is easier to implement. It can use the origin hints' infrastructure as much as possible.
+3. It can support almost all the hints which can take effect in the query block. Oracle can only support the join order, join method and access path hints.
+
+Cons:
+1. It may not be easy to write the query block name hint for a view.
+2. The user should define the query block name hint first.
