[jira] [Created] (CASSANDRA-16048) Safely Ignore Compact Storage Tables Where Users Have Defined Clustering and Value Columns

Jordan West created CASSANDRA-16048:
---------------------------------------

             Summary: Safely Ignore Compact Storage Tables Where Users Have Defined Clustering and Value Columns
                 Key: CASSANDRA-16048
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16048
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Jordan West
            Assignee: Jordan West


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.
