jiaan.geng created SPARK-44781: ---------------------------------- Summary: Runtime filter should supports reuse exchange if it can reduce the data size of application side Key: SPARK-44781 URL: https://issues.apache.org/jira/browse/SPARK-44781 Project: Spark Issue Type: New Feature Components: SQL Affects Versions: 4.0.0 Reporter: jiaan.geng
Currently, Spark runtime filter only supports using the subquery on one table. In fact, we can reuse the exchange, even if it is a shuffle exchange. If the shuffle exchange come from a join which has one side with selective predicates, so the results of the join can be used to prune the data amount of the application side. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
