Kenneth Knowles updated BEAM-1119:
----------------------------------
Component/s: beam-model-runner-api
beam-model
> Add a trigger that fires when the watermark passes timestamp
> ------------------------------------------------------------
>
> Key: BEAM-1119
> URL: https://issues.apache.org/jira/browse/BEAM-1119
> Project: Beam
> Issue Type: Improvement
> Components: beam-model, beam-model-runner-api, sdk-java-core
> Reporter: Manu Zhang
> Assignee: Kenneth Knowles
>
> For a pane with elements and timestamps {{[(a, 1), (b, 4), (c, 5)]}},
> * "a" would be emitted if watermark passes 1
> * "a" and "b" would be emitted if watermark passes 4
> * all the elements would be emitted if watermark passes 5
> * if the watermark jumps from 0 to 7 then all the elements would be emitted
> * if "d" comes in late with timestamp 3, then it will be emitted if it's within the allowed
lateness.
> This usually means the trigger fires in the middle of a window and is useful when firing
at the end of window misses the latency requirement.
