Rafty is yet another golang library that manage to replicate log state machine. Details about Raft protocol can be found here

Reading this documentation is recommanded before going any further.

There are many libraries out there implementing the search of an understandable consensus algorithm. Unfortunately, I mostly found them difficult to understand as there is not so much clear documentation about how to use them. As examples, we have production ready repositories like:

• https://github.com/hashicorp/raft
• https://github.com/etcd-io/raft

So let's try to redo the wheel with more explanations.

Here is a list of the supported features of rafty:

• Prevote election
• Leader election
• [] Write log on storage
• [] Log replication
• [] Log compaction
• [] Membership changes
  • Add member
  • remove member
  • promote member
