Thought about it a little more. The spout should probably just check when
it polls messages that the messages are not behind the committedOffset. If they
are, the committedOffset needs to move to the left.
It's a little irritating that the consumer doesn't expose an API to let the
client know that an unclean leader election happened. It would be nice if for
example ConsumerRebalanceListener had a method to tell the client to roll back
the committed offset to the new LEO after an unclean leader was elected.
