>             Project: Flink
>          Issue Type: Sub-task
>          Components: Table API & SQL
>    Affects Versions: 1.3.0

>            Priority: Critical

> The OVER windows have been implemented by several contributors.
> We should do a post pass over the contributed code and improve a few things.
> * Functionality
> ** Currently every time attribute is allowed as ORDER BY attribute. We must check that
this is actually a time indicator ({{procTime()}}, {{rowTime()}}) and that the order is ASCENDING.
> * Documentation
> ** Add documentation for OVER windows
> * Code style
> ** Consistent naming of {{ProcessFunctions}} and methods
> * Tests
> ** Move the OVER window tests out of SqlITCase into a dedicated class
> ** Move the OVER window tests out of WindowAggregateTest into a dedicated class
> ** Add tests based on the test harness for all {{ProcessFunctions}} similar to {{BoundedProcessingOverRangeProcessFunction}}.
The tests should include exact boundary checks for range windows and check for proper parallelization
with multiple keys.
