Deegue created SPARK-29910: ------------------------------ Summary: Add minimum runtime limit to speculation Key: SPARK-29910 URL: https://issues.apache.org/jira/browse/SPARK-29910 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 3.0.0 Reporter: Deegue
The minimum runtime to speculation used to be a fixed value 100ms. It means tasks finished in seconds will also be speculated and more executors will be required. To resolve this, we add `spark.speculation.minRuntime` to control the minimum runtime limit for speculation. We can reduce normal tasks to be speculated by adjusting `spark.speculation.minRuntime`. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
