if you have a namespace with, say, 2 bundles and 1 partitioned topic composed of 16 partitions,
you should expect that each bundle will contain roughly the same number of partitions (depending
on where the hashing falls).

   Yes, my question is about this. If the bundle only contains one partition and the partition
is still overloaded, is there a way to solve it? Increasing partition does not work for me
cause I use key hash as the routing mode while producing the messages.
