Attila Doroszlai commented on HDDS-8282:
----------------------------------------
[~hemantk], I think {{RocksDBCheckpointDiffer}} should
# be closed from {{RDBStore#close}} before DB is closed
# keep track of closed state
# ignore compaction events after it has been closed
Do you mind if I take this?
