Multiple state machines

Is it possible to have multiple statemachines for a single raft group id? So I can have the same writes go to multiple DBs?

Regards,
Asad

Yes.  We could implement a StateMachine using the composite pattern ( https://en.wikipedia.org/wiki/Composite_pattern ).  The composite StateMachine forwards the writes to its child StateMachine(s).
