---------------------------------------------------------------

There is a problem with the method restoreState. It is only possible to restore 
the state of the last snapshot by reconnecting to the RabbitMQ Queue. If a 
worker node crashes and the connection to RabbitMQ is lost, then the messages 
which are not acknowledged by the worker node will be sent to other consumers.

Does it cause any problems if it is only possible to restore the state of the 
last snapshot?

> The RabbitMQ connector does not offer any fault tolerance guarantees right 
> now, because it does not participate in the checkpointing.
> We should integrate it in a similar was as the {{FlinkKafkaConsumer}} is
