> While implementing a test case for the Kafka Consumer, I came across the following bug:
> Consider the following topology, with the operator parallelism in parentheses:
> Source (2) --> Sink (1).
> In this setup, the {{snapshotState()}} method is called on the source, but not on the Sink.
> The sink receives the generated data.
> The only one of the two sources is generating data.
> I've implemented a test case for this, you can find it here: https://github.com/rmetzger/flink/blob/para_checkpoint_bug/flink-tests/src/test/java/org/apache/flink/test/checkpointing/ParallelismChangeCheckpoinedITCase.java
