Reorder tasks by input size can save the whole stage execution time. Let's say we have one stage with 4 tasks and the `defaultParallelism` is 2 and the 4 tasks have differnt execution time with [1s, 3s, 2s, 4s]. * in normal the execution time of the stage is: 7s * after reorder the tasks, the execution time of the stage is: 5s a new config `spark.scheduler.reorderTasks.enabled` to decide if we allow to reorder tasks. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
