Raghu Angadi commented on BEAM-6333:
------------------------------------
Thanks Jan. I agree with everything in the above comment. 2 seconds is
decumented in JavaDoc for `withLogAppendTime()`
I know it is fairly straight forward option to add ... Since you have a work
around for now, I will close this for now, though I am not strongly opposed to
it. It might come up again and we might end up adding it then.

> For pipelines that require the emitted watermarks to be absolutely correct
> the current behavior using 2 seconds timeout could lead to problems.
> Therefor it should be possible to disable this behavior. While changing the
> code the hardcoded 2 seconds can also be made configurable. (There's already
> a TODO about that in the code.)
>
> A (preliminary) PR making this change is available:
> https://github.com/apache/beam/pull/7382.
