Marcus Olsson updated CASSANDRA-13084:
--------------------------------------
Attachment: CASSANDRA-13084-3.X.patch
CASSANDRA-13084-3.0.patch
Attaching patches for 3.0 and 3.X. The 3.X version should apply cleanly to
trunk.
Unfortunately I have not been able to run the dtests locally with these patches
as I seem to have some issues with my setup.
> Avoid byte-array copy when key cache is disabled

> Key: CASSANDRA-13084

> Project: Cassandra

>
> 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.
