> Counter cache still uses a concurrent map on-heap. This could go to off-heap 
> and feels doable now after CASSANDRA-8099.
> Evaluation should be done in advance based on a POC to prove that pure 
> off-heap counter cache buys a performance and/or gc-pressure improvement.
> In theory, elimination of on-heap management of the map should buy us some 
> benefit.
