…tor#9992) Summary: Gluten project needs to pre-build arrow before building velox. And it's also possible that arrow libs have already been installed, e.g., via vcpkg. Then, velox doesn't need to build arrow from source again.

Summary: This change adds compatibility with newer versions of Protobuf. The actual version of Protobuf is not being updated. Protobuf v27.2 was used for testing. Protobuf v21.8 is still supported.

Summary: At present, RowNumber only supports single-level spill partitions. Once a spill takes place, it won't be spilled again. This means that even if a restored spill partition uses an excessive amount of memory, it still cannot be reclaimed. Therefore, it would be beneficial to implement recursive spill support, as outlined in https://facebookincubator.github.io/velox/develop/spilling.html. 1 Advance 'spillPartitionBits_' based on the partition bit of the currently restoring spill partition to prepare for potential subsequent spills (recursive). 2 During the recursive spill input process, read the spilled input data from the previous spill run via 'spillInputReader_', then spill it back into several sub-partitions. Then restore one of the newly spilled partitions and reset 'spillInputReader' accordingly. 3 It's crucial to separate the recursive input spill process from the spill process itself, as it can be time-consuming and should yield if it exceeds the CPU time limit. In summary, the first spill operation writes all data to the disk. Subsequently, RowNumber reads the data from the disk one partition at a time and clears the data from the restored partition once it has been processed (facebookincubator#8413). In the case of a recursive spill, only the data from the currently restored partition in memory is spilled to the disk (next level), and only one partition from the next level is loaded back into memory. The data layout may look like as follows. ||Memory|Disk| | -- | -- | -- | |No-Spill | [P0, P1]| []| |First Spill | []| [P0, P1]| |Restore | [P0] | [P1]| |Second Spill | [] | [P0-0, P0-1, P1]| |Restore| [P0-0] | [P0-1, P1]| |Processed |[] |[P0-1, P1]| |Restored |[P0-1] |[P1]| |Processed | [] | [P1]| |Restored | [P1] | []| Pull Request resolved: facebookincubator#8654 Reviewed By: oerling Differential Revision: D54493422 Pulled By: xiaoxmeng fbshipit-source-id: 40dc02180d7fce46131fe98f68a00a776caceccc
…tor#10260) Summary: This PR solves the following issues: 1. `cumulativeBytes_` is the counter of allocated bytes, if we allocate n blocks and then execute free() on these blocks, the final value of `cumulativeBytes_` should be equal to 0. But without this PR, the value of `cumulativeBytes_` is not equal to 0. see `HashStringAllocatorTest#multipleFreeAncCheckCumulativeBytes` test case in this PR. This is because we don't include the size of the `Header` when calculating the allocated bytes. 2. When executing `HashStringAllocator::clear()`, we need to decrement memory counters. PR facebookincubator#10053 only decrement memory counters when releasing `allocationsFromPool_`. We also need to decrement the memory counters when releasing memory requested by `memory::AllocationPool`. 3. After executing `HashStringAllocator::clear()`, the values of `cumulativeBytes_` and `sizeFromPool_` should be equal to 0.

Summary: Pull Request resolved: facebookincubator#10344 There is a lot more clean up to be done in this file, this just targets a single test fixture. Velox functions now support the logical type TimeStampWithTimeZone. The use of "evaluateWithTimestampWithTimezone" is therefore no longer needed.

Summary:
boost::lexical_cast used to implement cast(uuid as varchar) is very slow.
Replace with custom optimization.
Microbenchmark shows 20x improvement.
The benchmark compares uuid() with cast(uuid() as varchar). The latter includes the code of the former plus the cost of the cast. Before the change, uuid() + cast was 16s, 10s more than uuid() alone. After the change, uuid() + cast() is just 0.5s more.
Before:
```

After:
