[jira] [Commented] (SPARK-10291) Add statsByKey method to compute StatCounters for each key in an RDD
[ https://issues.apache.org/jira/browse/SPARK-10291?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15064266#comment-15064266 ] Sean Owen commented on SPARK-10291: --- My POV is that this isn't likely worth adding a method for. I appreciate the value of utility methods but have to weight it against adding another item to a core API and how often it'd be used. This is also straightforward to express in Spark SQL on a dataframe, no? > 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 >Priority: Minor > > A common task is to summarize numerical data for different groups.
