Yanqin Jin 241b5aa15a Timestamp-based validation for pessimistic txn (#9562) ... Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/9562 With per-transaction `read_timestamp_`, it is possible to perform transaction validation after locking a key in addition to sequence-based validation. Specifically, if a transaction has a read_timestamp, then we perform timestamp-based validation as well after the key is locked via `GetForUpdate()`. This is to make sure that no other transaction has modified the key and committed successfully since the read timestamp (but before the locking operation) which represents a consistent view of the database.
