Kraft 🦀

Kraft is a distributed, strongly consistent Key-Value store implemented in Rust. It relies on the Raft consensus algorithm to manage log replication and ensure fault tolerance across a cluster of nodes.

Designed for performance and safety, Kraft aims to provide a reliable storage solution while leveraging Rust's memory safety guarantees and asynchronous capabilities.

⚠️ Note: This project is currently under active development (WIP).

🌟 Key Features

• Raft Consensus: Implements Leader Election, Log Replication, and Safety guarantees.
• Strong Consistency: Ensures that all committed data is consistent across the cluster.
• Fault Tolerance: The system remains operational as long as a quorum (majority) of nodes are available.
• Async I/O: Built on top of Tokio for high-performance non-blocking networking.
• Persistent Storage: Logs and state are persisted to disk to survive crashes.
• Simple API: Basic GET, PUT, and DELETE operations.

ARCHITECTURE

Kraft follows the standard Raft architecture:

1. Leader: Handles all client requests and replicates log entries to followers.
2. Follower: Passive node that responds to requests from leaders and candidates.
3. Candidate: A node attempting to become the new leader.

Communication between nodes is handled via gRPC (or TCP/UDP depending on implementation), ensuring efficient serialization of Raft RPCs (RequestVote, AppendEntries).
