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

    [ https://issues.apache.org/jira/browse/BEAM-2140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16065663#comment-16065663
] 

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.

to unblock the open PR for BEAM-1763.
