akankshamahajan fbd2f563bb Add an interface to provide support for underlying FS to pass their own buffer during reads (#11324) ... Summary: 1. Public API change: Replace `use_async_io` API in file_system with `SupportedOps` API which is used by underlying FileSystem to indicate to upper layers whether the FileSystem supports different operations introduced in `enum FSSupportedOps `. Right now operations are `async_io` and whether FS will provide its own buffer during reads or not. The api is changed to extend it to various FileSystem operations in one API rather than creating a separate API for each operation. 2. Provide support for underlying FS to pass their own buffer during Reads (async and sync read) instead of using RocksDB provided `scratch` (buffer) in `FSReadRequest`. Currently only MultiRead supports it and later will be extended to other reads as well (point lookup, scan etc). More details in how to enable in file_system.h Pull Request resolved: https://github.com/facebook/rocksdb/pull/11324 Test Plan: Tested locally Reviewed By: anand1976 Differential Revision: D44465322 Pulled By: akankshamahajan15 fbshipit-source-id: 9ec9e08f839b5cc815e75d5dade6cd549998d0ec		2023-06-23 11:48:49 -07:00
