When you state the numbers, are they the same across instances in the
cluster, meaning that Topic-0 would have 910*5 GB in source cluster and
25*5 GB in target cluster?
Another possibility is that MirrorMaker uses compression on the producer
side, but I would be surprised if the compression rate could be 25/910.
