[jira] [Commented] (HDDS-12502) Enable compaction on all other snapshot tables excepting for KeyTable/FileTable/Directory

    [ https://issues.apache.org/jira/browse/HDDS-12502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17946888#comment-17946888 ] 

Wei-Chiu Chuang commented on HDDS-12502:
----------------------------------------

[~swamirishi]is the compaction supposed to happen when a snapshot is created? Once a snapshot is created it should be immutable and no need to compact any more?

> Leaving FileTable, DirectoryTable and keyTable we should enable compaction on all other tables. If there is a snapshot where there is a lot of keys that can be reclaimed there would be significant amount of data that would get added to deletedKeyTable and deletedDirectory table and would be eventually removed as well. We should allow compactions to reduce the rocksdb size.
