How to control number of regions that are moved during balance
operation?
Currently when the load balancer runs, it returns a list of plans to
AssignmentManager, and it immediately executes all plans. It is very
disruptive for our operations. Is there anyway I can ask Assignment manager
to execute only few plans at a time? Once it finishes all smaller region
plans, it continues with next set of plans.

Hi Gomes,
Apart from what has already been replied (see Ted's link) you can do your
own balancer. Just extend the existing one, overwrite balanceCluster method
where you call the super but return only a subset of the returned list?
