                 URL: https://issues.apache.org/jira/browse/HDDS-1564
             Project: Hadoop Distributed Data Store
          Issue Type: New Feature

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 worn in this feature also related to HDDS-700 which implements rack-aware container
placement for closed containers.
