> Interrupt cache prefetch thread when a heap usage threshold is reached

> Key: HBASE-28303
> URL: https://issues.apache.org/jira/browse/HBASE-28303
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 2.6.0, 2.4.17, 3.0.0-beta-1, 4.0.0-alpha-1, 2.5.7, 2.7.0
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Major
> Fix For: 3.0.0, 4.0.0-alpha-1, 3.0.0-beta-2
>
>
> Mostly critical when using non heap cache implementations, such as offheap or
> file based. If the cache medium is too large and there are many blocks to be
> cached, it may create a lot of cache index object in the RegionServer heap.
> We should have guardrails to preventing caching from exhausting available
> heap.
