Davies Liu created SPARK-13213: ---------------------------------- Summary: BroadcastNestedLoopJoin is very slow Key: SPARK-13213 URL: https://issues.apache.org/jira/browse/SPARK-13213 Project: Spark Issue Type: Improvement Reporter: Davies Liu
Since we have improve the performance of CartisianProduct, which should be faster and robuster than BroacastNestedLoopJoin, we should do CartisianProduct instead of BroacastNestedLoopJoin, especially when the broadcasted table is not that small. Today, we hit a query that take very long time but still not finished, once decrease the threshold for broadcast (disable BroacastNestedLoopJoin), it just finished in seconds. -- 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
