Al M updated SPARK-24306: ------------------------- Summary: Sort a Dataset with a lambda (like RDD.sortBy) (was: Sort a Dataset with a lambda (like RDD.sortBy() )) > Sort a Dataset with a lambda (like RDD.sortBy) > ---------------------------------------------- > > Key: SPARK-24306 > URL: https://issues.apache.org/jira/browse/SPARK-24306 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.3.0 > Reporter: Al M > Priority: Minor > > Dataset has many useful functions that do not require hard coded column names > (e.g. flatMapGroups, map). Currently the sort() function requires us to pass > the column name as a string. > It would be nice to have a function similar to the sortBy in RDD where i can > define the keys in a lambda e.g. > {code:java} > ds.sortBy(record => record.id){code} -- 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
