Fabian Hueske commented on FLINK-4683:
--------------------------------------

Hi [~sunjincheng121], thanks for picking up this issue.
FLIP-11 mainly describes the API for this feature, not the internal implementation.

So far none of the row windows (FLINK-4678 and FLINK-4679) has been implemented.
The other issues are assigned to [~jark] and [~twalthr].

I think we should first agree on a joint architecture before starting with an implementation. 
We also should keep in mind, that some types of row windows are already supported by Calcite (as SQL OVER). Ideally, the execution code can be reused to process SQL windows as well.

What do you think [~sunjincheng121], [~jark], [~twalthr]?
