Benedict commented on CASSANDRA-11452:
--------------------------------------
If we had direct access to the hash table, the hash collision check could be
made almost entirely free. As it stands, I don't think it can be done at all
without a parallel structure which would be costly to maintain.

> Following up from CASSANDRA-5863, to make best use of caching and to avoid
> having to explicitly marking compaction accesses as non-cacheable, we need a
> cache implementation that uses an eviction algorithm that can better handle
> non-recurring accesses.
