One other thing maybe we can fix here. In `ReplicatedLog.validateOffsetAndEpoch`, we have the following check: ``` } else if ( earliestSnapshotId().isPresent() && ((offset < startOffset()) || (offset == startOffset() && epoch != earliestSnapshotId().get().epoch) || (epoch < earliestSnapshotId().get().epoch)) ) { ``` We probably should be caching the result of `earliestSnapshotId`. This is probably one reason it was killing performance. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
