Kenneth Knowles commented on BEAM-3749:
---------------------------------------
I think this link will clarify:
https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/transforms/windowing/Window.java#L333
The trigger is left alone if you use {{Window.into}} when the SQL sets up the
window function. It will not set it to the {{DefaultTrigger}}.
> support customized trigger/accumulationMode in BeamSql

> Currently BeamSql use {{DefaultTrigger}} for aggregation operations.
> By adding two options {{withTrigger(Trigger)}} and
> {{withAccumulationMode(AccumulationMode)}}, developers can specify their own
