liupc edited a comment on issue #27871: [SPARK-31105][CORE]Respect sql execution id for FIFO scheduling mode URL: https://github.com/apache/spark/pull/27871#issuecomment-602373911 Thanks @dongjoon-hyun , let's spill the scopes, and add an option to respect `jobGroup` level priority in the `core` module. And I think even in current approach, the congestion issue is serious, so this PR is not about to solve it, but I proposed another PR for this: https://github.com/apache/spark/pull/27862 I really think this is helpful for OLAP senarios, and we test this in real workloads in xiaomi.
