> In the DB listeners (in RocksDBCheckpointDiffer), we could:
> 1. Only track the compaction when there is at least one snapshot in OM DB 
> (should be easily doable when snapshot chain is implemented)
> 2. Track only the relevant tables' SSTs (keyTable, fileTable, 
> directoryTable), ignoring others -- possibly with some checks by calling RDB 
> APIs.
