Apache Spark reassigned SPARK-10291: ------------------------------------ Assignee: Apache Spark > Add statsByKey method to compute StatCounters for each key in an RDD > -------------------------------------------------------------------- > > Key: SPARK-10291 > URL: https://issues.apache.org/jira/browse/SPARK-10291 > Project: Spark > Issue Type: New Feature > Components: PySpark > Reporter: Erik Shilts > Assignee: Apache Spark > Priority: Minor > > A common task is to summarize numerical data for different groups. Having a > `statsByKey` method would simplify this so the user would not have to write > the aggregators for all the statistics or manage collecting by key and > computing individual StatCounters. > This should be a straightforward addition to PySpark. I can look into adding > to Scala and R if we want to maintain feature parity. -- 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
