[jira] [Commented] (CASSANDRA-8928) Add downgradesstables

    [ https://issues.apache.org/jira/browse/CASSANDRA-8928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17718819#comment-17718819 ] 

Claude Warren commented on CASSANDRA-8928:
------------------------------------------

I also encountered the bigV3 problem and fixed that in a later push.    The problem I am trying to solve is to remove columns that were added to system tables between 3 and 4.   I also think there were some format changes that need to be undone.

> As mentioned in other places such as CASSANDRA-8047 and in the wild, sometimes you need to go back.  A downgrade sstables utility would be nice for a lot of reasons and I don't know that supporting going back to the previous major version format would be too much code since we already support reading the previous version.
