> As part of initial implementation of RocksDBCheckpointingDiffere, snapshotID was added to [CompactionNode|https://github.com/apache/ozone/pull/3824/files#diff-1d5c6c892a2d24d85ca002dafcb9f39341192baaa7b5323d2325b5fc7a238c7fR246] for debugging. Now in [change#5317|https://github.com/apache/ozone/pull/5317], we migrated to RocksDB to store it and also keep DB *transactionId*. The other problem is how to get *snapshotId*. You can argue and use *snapshotChainManager*  but it will create circular dependency unless setter is used (which is not a nice way).
> Hence as part of this jira, we can remove *snapshotId* from the compaction log and just rely on *transactionId*.
