Comment: was deleted
(was: Have a look at the interface of the [user-defined aggregate functions|https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/table/udfs.html#aggregation-functions].
Incremental windows use {{accumulate()}} and {{retract()}} to add and remove values from an

> Since OVER windows are supported for streaming tables, this issue is not about the API
(which is available) but about adding the execution strategies and translation for OVER windows
on batch tables.
