Reynold Xin commented on SPARK-3862: ------------------------------------ David, Thanks. Let's chat there. Since I created the ticket, I have new thoughts on how we can make something better with codegen, rather than writing specialized operators. > MultiWayBroadcastInnerHashJoin > ------------------------------ > > Key: SPARK-3862 > URL: https://issues.apache.org/jira/browse/SPARK-3862 > Project: Spark > Issue Type: Sub-task > Components: SQL > Reporter: Reynold Xin > > It is common to have a single fact table inner join many small dimension > tables. We can exploit this fact and create a MultiWayBroadcastInnerHashJoin > (or maybe just MultiwayDimensionJoin) operator that optimizes for this > pattern. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
