Sean Owen updated SPARK-3917: ----------------------------- Fix Version/s: (was: 1.1.0) > Compress data before network transfer > ------------------------------------- > > Key: SPARK-3917 > URL: https://issues.apache.org/jira/browse/SPARK-3917 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 1.1.0 > Environment: All > Reporter: junlong > > When training Gradient Boosting Decision Tree on large sparse data, heavy > network flow pull down CPU utilization ratio. And through compression on > network flow data, 90% are reduced. > So maybe compression before transfering may provide higher speedup on > spark. And user can configure it to decide whether compress or not. -- 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
