Github user uce commented on the issue: https://github.com/apache/flink/pull/2158 Good job Chesnay! Reads very well. I like the way the text and code examples are mixed. I had some minor inline comments. My biggest concern (not reflected in the inline comments) is the `Scope` section, which is too dense in my opinion. Do you think we can improve it somehow? Maybe add sub sections `System Scope`, `User Scope`, `Examples`, `Variables` for starters. The `hierarchical orders` stuff I did not get.
