 Description   

Add support for multiple migration destination managers per collection on the same shard. That way a single shard can serve as a recipient of multiple incoming chunks.

Having this feature allows sharing to support fast rebalancing when a small number of shards are added to relieve an already loaded cluster.

To clarify, this feature is to implement multiple incoming migrations for the same shard/collection. I have updated the description.
