----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Respect sql execution id when scheduling taskSets
> -------------------------------------------------
>
> Key: SPARK-31105
> URL: https://issues.apache.org/jira/browse/SPARK-31105
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.1.0
> Reporter: liupengcheng
> Priority: Major
>
> Currently, spark will sort taskSets by jobId and stageId and then schedule
> them in order for FIFO schedulingMode. In OLAP senerios, especially under
> high concurrency, the taskSets are always from different sql queries and
> several jobs can be submitted for execution at one time for one query for
> adaptive execution. But now we order those taskSets without considering the
> execution group, which may causes the query being delayed.
> So I propose to consider the sql execution id when scheduling jobs.
