rs-raft

This is an implementation of Raft consensus algorithm referring the respected paper.

How to run

• Run process

RUST_LOG=info RAFT_RPC_PORT=8090 OTHER_NODES=localhost:8070,localhost:8080 cargo run

• Run tests

RUST_LOG=info cargo test

Concept

• This implementation is inspired from the Kubernetes reconcile loop.

  • raft_reconciler.rs has a loop which reconciles rpc and data periodically according to the Raft state.

• Each Raft process connects with others via gRPC.

  • raft_server.rs is the server and raft_client.rs is the client implementation.

• All the business logic of the consensus algorithm is placed in raft_state.rs.

Not implemented features

• State snapshot
• Cluster membership changes
