> Key: BEAM-912
> URL: https://issues.apache.org/jira/browse/BEAM-912
> Project: Beam
> Issue Type: New Feature
> Components: sdk-ideas

>
> 1.We can support some data-driven trigger, so we need expose data in
> OnElementContext of onElement method.
> 2.We can support more flexible join, so we need expose buffer tag in
> TriggerContext, now this buffer tag is in SystemReduceFn.
> for example: SELECT STREAM * FROM Orders AS o JOIN Shipments AS s
> ON o.orderId = s.orderId AND s.rowtime BETWEEN o.rowtime AND o.rowtime +
> INTERVAL '1' HOUR;
