Review Comment:
is there a reason why we need to store all the offsets in these nested maps?
If we are just going to commit all the data anyway? I was wondering if the same
would be accomplished if we had a list of all the info for each producer id. I
guess it is the same complexity. I was just curious if we ever needed access
for a random specific partition for a given producer ID.
