> Add option for unlimited phoenix.query.QueueSize

> Key: PHOENIX-7213
> URL: https://issues.apache.org/jira/browse/PHOENIX-7213
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Tanuj Khurana
> Assignee: Tanuj Khurana
> Priority: Major
> Fix For: 5.2.0
>
>
> As discussed in PHOENIX-7117 _*phoenix.query.queueSize*_ limits can cause
> scan queries on table with lot of regions to fail. I did some profiling and
> found that each task allocates 48 bytes. So I am adding an enhancement to
> make the queue size unlimited if we set the limit to -1. We still have a
> limit on the number of tasks that can be executed in parallel controlled by
> the
> _*phoenix.query.threadPoolSize*_
>
> If you don't enforce the limit, the only thing that is limiting is the jvm
> heap allocated.
