Description
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.
