public class ClusterSnapshotRecord
extends WALRecord

ClusterSnapshot record. It splits WAL on 2 areas: any data changes before this record are part of related ClusterSnapshot, and vice versa. It's guaranteed with: 1. The record is written after ClusterSnapshot acquires checkpoint writeLock. 2. The writeLock is acquired on PME, after every transaction already committed and no active transactions anymore.
