Fabian Hueske updated FLINK-6257:
---------------------------------
Description:
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.
