-----------------------------------

             Summary: Support group windows over intervals of months 
                 Key: FLINK-9740
                 URL: https://issues.apache.org/jira/browse/FLINK-9740
             Project: Flink
          Issue Type: New Feature
          Components: Table API &amp; SQL
            Reporter: Timo Walther


Currently, time-based group windows can be defined using intervals of milliseconds such as
{{.window(Tumble over 10.minutes on 'rowtime as 'w)}}. For some use cases it might useful
to define windows of months (esp. in event-time) that work even with leap years and other
special time cases.

The following should be supported in Table API & SQL:

{{.window(Tumble over 1.month on 'rowtime as 'w)}}
