damccorm opened a new issue, #21606: URL: https://github.com/apache/beam/issues/21606
See the dev mail list thread for details: https://lists.apache.org/thread/ps3m0jc0ngqp1y2s0mv2n6hxhvgkr3vw PeriodicImpluse transform in Java sdk generates unbounded PCollection; while in Python sdk it generates bounded PCollection. The latter case may cause issues in streaming. Per Cham: Note that the primary use-case of PeriodicImpulse (according to the design doc) was to generate a fixed/bounded input that can slowly change over time but changing over time dimension would make it unbounded. Seems like we need to make python PeriodicImpulse generates an unbounded pcoll, in alignment with Java implementation, and also make sure that the change does not break the current implementation of its original use case (stream enrichment problem).
