Marcelo Vanzin updated SPARK-26589: ----------------------------------- Component/s: (was: Spark Core) SQL > proper `median` method for spark dataframe > ------------------------------------------ > > Key: SPARK-26589 > URL: https://issues.apache.org/jira/browse/SPARK-26589 > Project: Spark > Issue Type: New Feature > Components: SQL > Affects Versions: 2.4.0 > Reporter: Jan Gorecki > Priority: Major > > I found multiple tickets asking for median function to be implemented in > Spark. Most of those tickets links to "SPARK-6761 Approximate quantile" as > duplicate of it. The thing is that approximate quantile is a workaround for > lack of median function. Thus I am filling this Feature Request for proper, > exact, not approximation of, median function. I am aware about difficulties > that are caused by distributed environment when trying to compute median, > nevertheless I don't think those difficulties is reason good enough to drop > out `median` function from scope of Spark. I am not asking about efficient > median but exact median. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
