Summary: support customized trigger/accumulationMode in BeamSql
Key: BEAM-3749
URL: https://issues.apache.org/jira/browse/BEAM-3749
Project: Beam
Issue Type: Improvement
Components: dsl-sql
Reporter: Xu Mingmin
Assignee: Xu Mingmin

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