> Based on comments from [~jingzhao], This jira tracks if we really need 3 maps in the
SCMNodeManager class or if we should collapse them to a single one. The reason why we have
3 maps is to reduce lock contention.  We might be able to collapse this into a single map.
This JIRA is to track that action item.
