| TiFlash | [`storage.format_version`](/tiflash/tiflash-configuration.md) | Modified | Introduces a new DTFile format `format_version = 5` to reduce the number of physical files by merging smaller files. Note that this format is experimental and not enabled by default. |
| TiDB Lightning | `tikv-importer.incremental-import` | Deleted | TiDB Lightning parallel import parameter. Because it could easily be mistaken as an incremental import parameter, this parameter is now renamed to `tikv-importer.parallel-import`. If a user passes in the old parameter name, it will be automatically converted to the new one. |
| TiDB Lightning | `tikv-importer.on-duplicate` | Deprecated | Controls action to do when trying to insert a conflicting record in the logical import mode. Starting from v7.3.0, this parameter is replaced by [`conflict.strategy`](/tidb-lightning/tidb-lightning-configuration.md#tidb-lightning-task). |
| TiDB Lightning | `conflict.max-record-rows` | Newly added | The new version of strategy to handle conflicting data. It controls the maximum number of rows in the `conflict_records` table. The default value is 100. |
| TiDB Lightning | `conflict.strategy` | Newly added | The new version of strategy to handle conflicting data. It includes the following options: "" (TiDB Lightning does not detect and process conflicting data), `error` (terminate the import and report an error if a primary or unique key conflict is detected in the imported data), `replace` (when encountering data with conflicting primary or unique keys, the new data is retained and the old data is overwritten.), `ignore` (when encountering data with conflicting primary or unique keys, the old data is retained and the new data is ignored.). The default value is "", that is, TiDB Lightning does not detect and process conflicting data. |
| TiDB Lightning | `conflict.threshold` | Newly added | Controls the upper limit of the conflicting data. When `conflict.strategy="error"`, the default value is `0`. When `conflict.strategy="replace"` or `conflict.strategy="ignore"`, you can set it as a maxint. |
| TiDB Lightning | `enable-diagnose-logs` | Newly added | Controls whether to enable the diagnostic logs. The default value is `false`, that is, only the logs related to the import are output, and the logs of other dependent components are not output. When you set it to `true`, logs from both the import process and other dependent components are output, and GRPC debugging is enabled, which can be used for diagnosis. |
