Assignee: Sanjeet Malhotra
> Add metrics for overall wall clock query wait time in Phoenix client thread
> pool and total time spent in executing HBase scan tasks
> -----------------------------------------------------------------------------------------------------------------------------------

> Key: PHOENIX-7528
> URL: https://issues.apache.org/jira/browse/PHOENIX-7528
> Project: Phoenix
> Issue Type: Improvement
> Affects Versions: 5.3.0
> Reporter: Sanjeet Malhotra
> Assignee: Sanjeet Malhotra
> Priority: Major
>
> Currently, we track task wait time and task end to end time for each HBase
> scan task. But when we try to consume these metrics we combine them by taking
> sum of these metrics across all the tasks. By taking sum of task wait time
> and task end to end time across all the tasks we are making these metrics non
> consumable if someone wants to know the wall clock time spent by query in
> Phoenix client thread pool or total wall clock time taken by HBase scan tasks.
> Thus, we can introduce two new metrics for the same. So, these two new
> metrics combined with TASK_EXECUTION_TIME metric can give us good indication
> of time spent in various stages in Phoenix client thread pool.
