Apache Spark reassigned SPARK-11914: ------------------------------------ Assignee: Apache Spark > [SQL] Support coalesce and repartition in Dataset APIs > ------------------------------------------------------ > > Key: SPARK-11914 > URL: https://issues.apache.org/jira/browse/SPARK-11914 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 1.6.0 > Reporter: Xiao Li > Assignee: Apache Spark > > repartition: Returns a new [[Dataset]] that has exactly `numPartitions` > partitions. > coalesce: Returns a new [[Dataset]] that has exactly `numPartitions` > partitions. Similar to coalesce defined on an [[RDD]], this operation results > in a narrow dependency, e.g. if you go from 1000 partitions to 100 > partitions, there will not be a shuffle, instead each of the 100 new > partitions will claim 10 of the current partitions. -- 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
