Davies Liu created SPARK-13354: ---------------------------------- Summary: Push filter throughout outer join when the condition can filter out empty row Key: SPARK-13354 URL: https://issues.apache.org/jira/browse/SPARK-13354 Project: Spark Issue Type: Improvement Components: SQL Reporter: Davies Liu Assignee: Davies Liu
For a query {code} select * from a left outer join b on a.a = b.a where b.b > 10 {code} The condition `b.b > 10` will filter out all the row that the b part of it is empty. In this case, we should use Inner join, and push down the filter into b. -- 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
