> 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}
