> 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.
