Subject [jira] [Created] (BEAM-3588) Reject invalid windowing configurations
Date Thu, 01 Feb 2018 06:46:00 GMT
Anton Kedin created BEAM-3588:
---------------------------------

             Summary: Reject invalid windowing configurations
                 Key: BEAM-3588
                 URL: https://issues.apache.org/jira/browse/BEAM-3588
             Project: Beam
          Issue Type: Improvement
          Components: beam-model
            Reporter: Anton Kedin


GBK (and consequently Beam SQL aggregations) rejects GlobalWindows+DefaultTrigger combination.

* are there more of known unsupported window/trigger combinations?
* can some version of this problem be solved analytically in general case?
* should there be a separate validation component on a higher level above GBK?
