> Apache Ratis supports multi-raft by allowing the same node to be a part of multiple raft groups. The proposal is to allow datanodes to be a part of multiple raft groups. The attached design doc explains the reasons for doing this as well a few initial design decisions. 
> Some of the work in this feature also related to HDDS-700 which implements rack-aware container placement for closed containers.
