Multi-raft

[akiradeveloper]

Real-world applications sometimes require multiple independent raft groups. This is called multi-raft. The most famous one is pingcap's tikv.

If the library maintains multiple raft applications inside the server instance, it will be very efficient because some resources (e.g. connection) or information (e.g. failure detection) can be shared between applications.

  subgraph server1
  GW1(gateway1)
  subgraph raft_lanes1
     RC11(group_id=1)
     RC12(group_id=2)
  end
  end

   subgraph server2
   GW2(gateway2)
   subgraph raft_lanes2
     RC21(group_id=1)
     RC22(group_id=2)
   end
  end
