[GitHub] [beam] kennknowles opened a new issue, #18646: Reject invalid windowing configurations

kennknowles opened a new issue, #18646:
URL: https://github.com/apache/beam/issues/18646

   GBK (and consequently Beam SQL aggregations) rejects GlobalWindows****DefaultTrigger combination.
   
   * are there more of known unsupported window/trigger combinations?
   * should Repeatedly.forever(AfterWatermark.pastEndOfWindow()) be allowed where DefaultTrigger isn't? At what level should this stop?
   * 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?
   
   Imported from Jira [BEAM-3588](https://issues.apache.org/jira/browse/BEAM-3588). Original Jira may contain additional context.
