> Key: HBASE-15542
> URL: https://issues.apache.org/jira/browse/HBASE-15542
> Project: HBase
> Issue Type: Improvement
> Components: Compaction
> Affects Versions: 2.0.0
> Reporter: Vladimir Rodionov
> Assignee: Vladimir Rodionov
>
> Compactions are CPU-bound, not I/O bound. We can mitigate this by increasing
> number of compaction threads for small and large compactions, but excessive
> object allocation limits maximum number of compaction threads we can use w/o
> bringing down RS due to very frequent GC cycles.
