Aljoscha Krettek commented on BEAM-2140:
----------------------------------------
I think to unblock this we have to move the SplittableDoFn implementation (in
Flink, I don't know about Dataflow) to a custom implementation that doesn't use
{{ProcessFn}} because stateful/timely DoFns are not a perfect fit right now. I
did this in this branch:
https://github.com/aljoscha/beam/tree/fix-flink-splittable-dofn-squashed It
works because we're now using Flink's processing-time timer facility directly,
which doesn't drop timers if they're late. This still has the issue of
processing-time timers being simply dropped when the pipeline shuts down (which
happens when the bounded source shuts down).
About the more thorny issues regarding watermarks and splittable DoFn I feel we
have to at least bring the discussion to the ML and somehow design us out of
the situation. 😃 What do you think?
