Yuming Wang updated SPARK-27714: -------------------------------- Target Version/s: (was: 3.0.0) > Support Join Reorder based on Genetic Algorithm when the # of joined tables > > 12 > -------------------------------------------------------------------------------- > > Key: SPARK-27714 > URL: https://issues.apache.org/jira/browse/SPARK-27714 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.1.0 > Reporter: Xianyin Xin > Assignee: Xianyin Xin > Priority: Major > > Now the join reorder logic is based on dynamic planning which can find the > most optimized plan theoretically, but the searching cost grows rapidly with > the # of joined tables grows. It would be better to introduce Genetic > algorithm (GA) to overcome this problem. -- 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
