Ekaterina Dimitrova commented on CASSANDRA-18799:
-------------------------------------------------
{quote}The changes are pretty substantial in terms of there being a lot of
refactoring to allow for multiple eviction policies. Previously I think there
was just LRU. There was also a lot of testing added, but we should expect this
to potentially be a major change and we don't test with row cache or test with
validating workloads like simulator.
Ideally we would test this with simulator and have simulator inject some chaos
into eviction so that we can force the eviction policies to evict things with
some distribution determined by simulator.

So, reading this, I understand you do not recommend the current upgrade,
[~aweisberg] before ensuring that mentioned testing is in place?
Also, thanks a lot for looking into this in great detail!
