Revision 66b5613d0c3f84e5ef72c43b62a2e9866efdde8a authored by sdong on 23 July 2019, 01:53:03 UTC, committed by Facebook Github Bot on 23 July 2019, 01:56:19 UTC
Summary: Right now, users cannot take advantage of row cache, unless no snapshot is used, or Get() is repeated for the same snapshots. This limits the usage of row cache. This change eliminate this restriction in some cases. If the snapshot used is newer than the largest sequence number in the file, and write callback function is not registered, the same row cache key is used as no snapshot is given. We still need the callback function restriction for now because the callback function may filter out different keys for different snapshots even if the snapshots are new.
