Subject [jira] [Created] (CASSANDRA-6351) When dropping a CF, row cache is not invalidated
Date Fri, 15 Nov 2013 14:49:21 GMT
Fabien Rousseau created CASSANDRA-6351:

             Summary: When dropping a CF, row cache is not invalidated
                 Key: CASSANDRA-6351
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Fabien Rousseau
            Priority: Trivial
         Attachments: 0001-invalidate-row-cache-when-dropping-CF.patch

When dropping a ColumnFamily with row cache enabled, then row cache is not invalidated for
this CF.

This can be a bit annoying if the ColumnFamily is recreated because it will be empty, but
row cache won't.
Note : this is similar to a "TRUNCATE" command (and TRUNCATE does invalidate the cache...)

Attached is patch which removes the rows of the currently dropped CF from row cache.
