The standard use of Raft is for implementing a fault tolerant, replicated state machine by means of a replicated log, maintained at each server within a replication group. Depending on the nature of the state we want to replicate, we can employ a simpler variant of Raft that achieves the same essential correctness properties. We can call this logless Raft and it can be useful when we are only replicating a single, small piece of state (e.g. configuration, metadata, etc.) between servers.
