URL: https://github.com/apache/spark/pull/24495#issuecomment-487904227
I filed https://issues.apache.org/jira/browse/SPARK-27604 to cover some improvements regarding constraints. This PR adds some improvement although there is room for more.
I'm interested in feedbacks about this PR and also in suggestions how we could take this further.
