Github user wuchong commented on the issue: https://github.com/apache/flink/pull/4263 Hi @fhueske , I left this comment under the JIRA. To make sure you know our situation, I post it here: >I think the most useful feature is PR3 "ORDER BY <any-attr> OFFSET FETCH" (i.e. TopN). It is an important requirement. And there is something more complex such as TopN for each group (e.g. https://stackoverflow.com/questions/176964/select-top-10-records-for-each-category). We have an idea (prototype) to support it, and planning to make a whole design for the TopN (any-attribute), and hope that to meet soon.
