Hyukjin Kwon resolved SPARK-2253. --------------------------------- Resolution: Incomplete > [Core] Disable partial aggregation automatically when reduction factor is low > ----------------------------------------------------------------------------- > > Key: SPARK-2253 > URL: https://issues.apache.org/jira/browse/SPARK-2253 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: Reynold Xin > Priority: Major > Labels: bulk-closed > > Once we see enough number of rows in partial aggregation and don't observe > any reduction, Aggregator should just turn off partial aggregation. This > reduces memory usage for high cardinality aggregations. > This one is for Spark core. There is another ticket tracking this for SQL. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
