# Raft
This library provides a simple, easy-to-understand, and reliable implementation of [Raft](https://en.wikipedia.org/wiki/Raft_(algorithm)) using Go. Raft is a [consensus](https://en.wikipedia.org/wiki/Consensus_(computer_science)) protocol designed to manage replicated logs in a distributed system. Its purpose is to ensure fault-tolerant coordination and consistency among a group of nodes, making it suitable for building reliable systems. Potential use cases include distributed file systems, consistent key-value stores, and service discovery.

# Protocol Overview
Raft is based on a leader-follower model, where one node is elected as the leader and coordinates the replication process. Time is divided into terms, and the leader is elected for each term through a leader election process. The leader receives client requests, which are then replicated to other nodes called followers. The followers maintain a log of all state changes, and the leader's responsibility is to ensure that all followers have consistent logs by sending them entries to append. Safety is guaranteed by requiring a majority of nodes to agree on the state changes, ensuring that no conflicting states are committed. 

# Future Features

The following features are currently in development or are intended to be added in the future:
- Batched log writes to improve disk I/O
- Membership changes
- Read-only operations

Other developers are encouraged to contribute to this project and pull requests are welcome.
