damccorm opened a new issue, #21133:
URL: https://github.com/apache/beam/issues/21133
An implementation of "equals" of the source seems to be expected/required
when doing a bounded read from an unbounded source. If doing so, logs are full
of warnings and fairly disturbing, see below. Same also applies, for instance,
to the Kafka Source.
Should KinesisSource (and dependencies) implement equals both in SDK v1 and
v2.
