------------------------------------------
For going on, could you add a test similar to {{CountTriggerTest}} and then
open a pull request?

> Hello,
> first Jira ticket that im opening here so if there is any mistakes of how
> doing it, please recorrect me.
> My suggestion is to add a TimeoutTrigger that apply as nestedTrigger(as
> example how the PurgeTrigger does).
> The TimeoutTrigger will support ProcessTime/EventTime and will have 2 timeous:
> # Const timeout - when the first element of the window is arriving it is
> opening a timeout of X millis - after that the window will be evaluate.
> # Continual timeout - each record arriving will increase the timeout of the
> evaluation of the window.
>
> I found it very useful in our case when using flink, and i would like to work
> on it (if it is possible).
> what do you think?
