> Operators should try/catch exceptions in the synchronous and asynchronous part of the checkpoint and send a {{DeclineCheckpoint}} message as a result.
> The decline message should have the failure cause attached to it.
> The checkpoint barrier should be sent anyways as a first step before attempting to make a state checkpoint, to make sure that downstream operators do not block in alignment.
