> Improve FlameGraphs scalability for high parallelism jobs
> ---------------------------------------------------------

> Key: FLINK-26074
> URL: https://issues.apache.org/jira/browse/FLINK-26074
> Project: Flink
> Issue Type: Improvement
> Reporter: Alexander Fedulov
> Assignee: Alexander Fedulov
> Priority: Major
> Labels: pull-request-available
>
> The FlameGraph feature added in FLINK-13550 issues 1 RPC call per subtask.
> This may cause performance problems for jobs with high paralleism and a lot
> of subtask running on the same TaskManager. It should be possible to improve
> this by grouping thread sampling requests using
> {code:java}
> ThreadMXBean.getThreadInfo(long[] ids, int maxDepth){code}
> instead of the currently used individual calls
> {code:java}
> ThreadMXBean.getThreadInfo(long id, int maxDepth){code}
