URL: https://issues.apache.org/jira/browse/SPARK-3655
Project: Spark
Issue Type: New Feature
Components: Spark Core
Affects Versions: 1.1.0

Priority: Minor
Now that spark has a sort based shuffle, can we expect a secondary sort soon?
There are some use cases where getting a sorted iterator of values per key is
helpful.
