Apache Spark commented on SPARK-12656: -------------------------------------- User 'gatorsmile' has created a pull request for this issue: https://github.com/apache/spark/pull/10630 > Rewrite Intersect phyiscal plan using semi-join > ----------------------------------------------- > > Key: SPARK-12656 > URL: https://issues.apache.org/jira/browse/SPARK-12656 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Reynold Xin > > Our current Intersect physical operator simply delegates to RDD.intersect. We > should remove the Intersect physical operator and simply transform a logical > intersect into a semi-join. This way, we can take advantage of all the > benefits of join implementations (e.g. managed memory, code generation, > broadcast joins). -- 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
