Ethan Rose commented on HDDS-4370:
----------------------------------

If we agree that we do not want to store deleted block data in RocksDB, I can 
make a new Jira to clean up some dead code. I believe the deleted blocks table 
and corresponding chunk info list codec are not being used now.

> Datanode deletion service can avoid storing deleted blocks
