Kenneth Knowles commented on BEAM-3749:
---------------------------------------
What about this?
{code}
PCollectionTuple inputTables = ...;
input.apply(Window.triggering(trigger).discardingFiredPanes()) // or
accumulatingFiredPanes
.apply(BeamSql.query("..."));
{code}
This should allow the CLI to apply the trigger and accumulation mode outside of
the SQL transform. This will use the continuation trigger the right way
everywhere.
> support customized trigger/accumulationMode in BeamSql

> Currently BeamSql use {{DefaultTrigger}} for aggregation operations.
> By adding two options {{withTrigger(Trigger)}} and
