…oken Summary: We have found in the S385274 that there is some con-currency issue when multiple thread try to access or update the Storage access token (BAT/SAT). This change currently introduce a lock mechanism to address this issue. Next steps: We have also seen that currently we call WS token service multiple time and override the token instead we can add a way to ensure that token is only fetched once. But this might require some changes in the way we use koski. As it might add an additional step to resolve the token once.

Summary: With this change, we now use lazy stats instead of eager stats. This affects both "ad-hoc" encoding selection, and "replay" encoding selection. I measured the performance of this change for "ad-hoc" encoding selection, and it seems negligible. Transforming a file with eager stats took 1m28s on average and the same was observed for lazy. Performance of captured encodings transform shows a big perf improvement, at 1m08s on average (~20% improvement).

Summary: Currently, stream chunking is implemented in the FieldWriter. However, field writer shouldn't know anything about how data is layed out in the file. This is the responsibility of the VeloxWriter layer. This change creates a clear separation between how FieldWriter is accumulating data and how VeloxWriter is later encoding/chunking the data. To do so, we introduce the concept of StreamData. FieldWriter is accumulating raw data in StreamData objects, and VeloxWriter is using these objects to decide when and how to flush. As part of this change, I had to also fix chunking for string types. Previously it was easy to disable string chunking, as FieldWriter had the context to identify string sata easily. With the new implementation, it is not that easy, so I opted for fixing string chunking. With this change I also introduced min size (configurable) for chunking, which prevents creating chunks that are too small.

Summary: Enabling optional parallel encoding during writes. NOTE: Currently, we added a mutex to the Buffer class, which will affect all callsites. In a future diff, we will change encodings to accept two buffers, one for internal temporary allocations, and another for the final encoded result. The internal buffer will not be thread safe, whereas the exteranl one will be, thus reducing the mutex contention.

…nfusion Summary: X-link: facebookincubator/velox#9244 A `TypeWithId` must be a proper tree without diamonds because each node references its parent. The constructor is reparenting the children, so taking shared ownership on children is misleading, especially when they are `const` qualified. With this change, the constructor will take `unique_ptr` of children so they will not be shared between multiple parents. Once the tree is constructed, the individual nodes is immutable and can be shared, so they are stored as `shared_ptr<const TypeWithId>` internally. bypass-github-export-checks Reviewed By: oerling Differential Revision: D55318609 fbshipit-source-id: 12098e76110e59d364fe7eaf8448cae46103b7ed

Summary: Our reader lifecycle tests verify that internal velox vectors and buffers are being reused as much as possible (as long as the caller is not holding a reference to these buffers). In these tests we verify that the pointer before and after calling next() is the same. However, for null buffers, they might still change, depending if the data contains nulls, vs not containing any nulls (in this case, we free the nulls vector). Since we randomly fuzz input buffers, we sometimes get parts of the vector containing no nulls and sometimes containing nulls, leading to a nulls buffer release/allocation, and this is failing the test. I changed the tests to only verify null pointers, if both sides are not null. Reviewed By: sdruzkin Differential Revision: D56361752 fbshipit-source-id: f6bc6b473c289bdd6ad88cace5c221fa6bf7886d
