Hi all, there is a pull request that I would like to bring back to life. It is related to the SQL programming guide and can be found here <https://github.com/apache/spark/pull/16329>.
I believe the PR should be helpful. The initial review is done already. Also, I updated it recently and checked that everything is still valid. Locally built docs (without APIs) can be found here <https://aokolnychyi.github.io/spark-docs/sql-programming-guide.html>. Thanks, Anton
