---------------------------------------
yuanboliu opened a new pull request, #6861:

Currently there are five modes in multiple subclusters like

Proposal a new mode called leader/follower mode. routers try to write to leader subcluster as many as possible. When routers read data, put leader subcluster into first rank.
