> Key: PHOENIX-4718
> URL: https://issues.apache.org/jira/browse/PHOENIX-4718
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Assignee: James Taylor
> Priority: Major
> Fix For: 4.14.0, 5.0.0
>
> Attachments: PHOENIX-4718-4.x-HBase-0.98.patch, PHOENIX-4718.patch,

>
> Since PHOENIX-4148, we track the heap size while aggregation is occurring.
> This decreased performance of aggregation by ~20%. We really only need to
> track this for the DistinctValueWithCountServerAggregator (used by DISTINCT
> COUNT, DISTINCT, PERCENTILE functions, and STDDEV functions). By
> conditionally tracking, we should be able to bring perf back to what it was
> before.
