This change allows an engine to recover from its local translog up to the given seqno. The extended API can be used in these use cases: When a replica starts following a new primary, it resets its index to the safe commit, then replays its local translog up to the current global checkpoint (see #32867). When a replica starts a peer-recovery, it can initialize the start_sequence_number to the persisted global checkpoint instead of the local checkpoint of the safe commit. A replica will then replay its local translog up to that global checkpoint before accepting remote translog from the primary. This change will increase the chance of operation-based recovery. I will make this in a follow-up. Relates #32867 |
