Benedict commented on CASSANDRA-11452:
--------------------------------------
Or, much more simply: maintain a CHM Iterator (i.e. in hash, or approximately
random, order) in a member variable. For 5% of _rejections above frequency 4_
step it forwards and use the next value as the guard.
I think this is the probably the simplest and most robust to all of the above
problems.

> 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.
