Summary: Cache ShuffleExchange RDD when the exchange is reused Key: SPARK-17574 URL: https://issues.apache.org/jira/browse/SPARK-17574 Project: Spark Issue Type: Improvement Components: SQL Reporter: Liang-Chi Hsieh We have the rule ReuseExchange to reuse exchange in the physical plan. However, for a ShuffleExchange we still need to retrieve remote blocks again when the shuffle exchange is reused. We can cache the RDD of the reused ShuffleExchange to avoid transferring remote blocks again. -- 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
