[jira] [Created] (CASSANDRA-13084) Avoid byte-array copy when key cache is disabled

Marcus Olsson created CASSANDRA-13084:
-----------------------------------------

             Summary: Avoid byte-array copy when key cache is disabled
                 Key: CASSANDRA-13084
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13084
             Project: Cassandra
          Issue Type: Bug
            Reporter: Marcus Olsson
            Assignee: Marcus Olsson
            Priority: Trivial


While profiling a cluster with the key cache disabled some unnecessary heap pressure was observed. It seems that even though the key cache is disabled we still create the *KeyCacheKey* object which uses _ByteBufferUtil.getArray()_ to copy the keys byte array.

I don't believe it's a big issue but it's still unnecessary when not using the key cache.
