Apache Spark commented on SPARK-13926: -------------------------------------- User 'JoshRosen' has created a pull request for this issue: https://github.com/apache/spark/pull/11755 > Automatically use Kryo serializer when shuffling RDDs with simple types > ----------------------------------------------------------------------- > > Key: SPARK-13926 > URL: https://issues.apache.org/jira/browse/SPARK-13926 > Project: Spark > Issue Type: Improvement > Components: Shuffle > Reporter: Josh Rosen > Assignee: Josh Rosen > > Because ClassTags are available when constructing ShuffledRDD we can use > them to automatically use Kryo for shuffle serialization when the RDD's types > are guaranteed to be compatible with Kryo (e.g. RDDs whose key, value, and/or > combiner types are primitives, arrays of primitives, or strings). This is > likely to result in a large performance gain for many RDD API workloads. -- 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
