This paper discusses a method for using erasure codes (specifically Reed-Solomon codes) to encode data stored in a Raft cluster to reduce the volume of storage and network traffic, while maintaining the failure-tolerance guarantees that Raft provides. We will briefly discuss the basics of Raft and erasure codes, and then talk through practical examples of how the cluster encodes, stores, and reconstructs data during different failure scenarios.
