Subject [jira] [Commented] (BEAM-2140) Fix SplittableDoFn ValidatesRunner tests in FlinkRunner
Date Tue, 27 Jun 2017 23:37:00 GMT


Kenneth Knowles commented on BEAM-2140:

Yes, your last comment is the reason. If the watermark of the Create doesn't advance past
_n_, then as far as ParDo(read forever) knows, it could receive a topic timestamped _n_ that
will result in pulling elements from pubsub timestamped _n_. So you have a stuck pipeline.
This highlights the issue we've discussed that a per-PCollection watermark is not really ideal
for SDF, but I think that scope is too big for this ticket.
