Raft is a distributed consensus algorithm widely used nowadays to build distributed applications like etcd. However, while it is even understandable than notorious Paxos algorithm it is still difficult to implement correct and efficient implementation.
This library is a Raft implementation based on Tonic, a gRPC library based on Tokio. By exploiting gRPC features like streaming, the inter-node log replication and snapshot copying is very efficient. Also, zero-copy ser/desr between replication stream and the log entries is another goal of this library in term of efficiency.
