Benedict commented on CASSANDRA-11452:
--------------------------------------
Just to clarify a mistake in the comments I wrote when hacking this together:
The distribution you printed was more correct (obviously, since it was
empirical). I only applied the division by 2 effect to the 0 bucket. The
progression is obviously 75%, 18.25%, 4.76%... (if I've just done my mental
arithmetic properly). It's the 1/2^N progression with pairs of probabilities
merged into 1 (by the division by 2).

> 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.
