-----------------------------------------
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.
