Apache Spark reassigned SPARK-36823: ------------------------------------ Assignee: (was: Apache Spark) > Support broadcast nested loop join hint for equi-join > ----------------------------------------------------- > > Key: SPARK-36823 > URL: https://issues.apache.org/jira/browse/SPARK-36823 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.3.0 > Reporter: XiDuo You > Priority: Major > > For the join if one side is small and other side is large, the shuffle > overhead is also very big. Due to the > bhj limitation, we can only broadcast right side for left join and left side > for right join. So for the other case, we can try to use > `BroadcastNestedLoopJoin` as the join strategy. -- 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
