Fabian Hueske commented on FLINK-4682:
--------------------------------------
Hi [~tonycox], row windows have not been implemented in Flink.
The first row window implementation will be quite a bit of effort because we
need to implement the API, validation, optimization and execution part.
A first approach would be to implement row windows (aka SQL OVER clause
windows) for SQL.
Then we would only need the optimization and execution parts.
> Add TumbleRow row-windows for batch tables.
