Robert Stupp resolved CASSANDRA-9738.
-------------------------------------
Resolution: Won't Fix
Fix Version/s: (was: 3.x)
Closed as won't-fix.
We already have CASSANDRA-11206 to handle large partitions and CASSANDRA-9754
is also making progress. Both tickets make this one somehow superfluous.
> Migrate key-cache to be fully off-heap
> --------------------------------------

> Key: CASSANDRA-9738
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9738
> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Robert Stupp
> Assignee: Robert Stupp
>
> Key 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.
