A minimal distributed key-value database with Hashicorp's Raft library

This technical article provides a step-by-step guide to implementing a basic distributed key-value store using Hashicorp's Raft consensus algorithm in Go. It explains the core concepts of Raft, demonstrates how to create a state machine for key-value operations, and shows how to expose the database via an HTTP API. The tutorial includes a complete, single-file code example of approximately 260 lines.
