[jira] [Comment Edited] (CASSANDRA-16048) Safely Ignore Compact
Storage Tables Where Users Have Defined Clustering and Value Columns
[ https://issues.apache.org/jira/browse/CASSANDRA-16048?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17194524#comment-17194524 ]

[~ifesdjeen] do you have a repro of that? I added some column level deletes in a [test I added previously | https://github.com/apache/cassandra/blob/cassandra-3.0/test/distributed/org/apache/cassandra/distributed/upgrade/CompactStorage2to3UpgradeTest.java#L190] and didn't discover any issues. Admittedly, it could be more robust and there may be a case I missed (aside: it would be nice to have Harry for this), but if you have a repro to share that would be super helpful. Thanks!

> Some compact storage tables, specifically those where the user has defined both at least one clustering and the value column, can be safely handled in 4.0 because besides the DENSE flag they are not materially different post 3.0 and there is no visible change to the user facing schema after dropping compact storage. We can detect this case and allow these tables to silently drop the DENSE flag while still throwing a start-up error for COMPACT STORAGE tables that don’t meet the criteria.
