    @revans2 no worries. Concerning your code snippet suggestion, I agree with 
most of it. We can definitely keep a lot of the state in the MessageId object. 
I agree it is indeed the ideal solution. I considered it initially but was 
concerned of how expensive it would be to keep all of that state in the 
MessageId.
    
    However, I don't think that Using the markAsDone(id) strategy will suffice 
to address the cases where tuples get acked out of order, and the cases were a 
sequence of tuples will get acked in sequence, but shifted from the last offset 
committed. In this scenario we need to have a way to keep track of the offset 
sequences that are ready to be committed. I still think that keeping `acked 
Map<TopicPartition, OffsetEntry>` will take care of this in an efficient way. 
If there is a better way, of course, I would totally welcome a suggestion.
