[FLINK-3399] CountWithTimeoutTrigger
----
> Count with timeout trigger
> --------------------------
>
> Key: FLINK-3399
> URL: https://issues.apache.org/jira/browse/FLINK-3399
> Project: Flink
> Issue Type: Improvement
> Reporter: Shikhar Bhushan
> Priority: Minor
>
> I created an implementation of a trigger that I'd like to contribute,
> https://gist.github.com/shikhar/2cb9f1b792be31b7c16e
> An example application - if a sink function operates more efficiently if it
> is writing in a batched fashion, then the windowing mechanism + this trigger
> can be used. Count to have an upper bound on batch size & better control on
> memory usage, and timeout to ensure timeliness of the outputs.
