yeeKV: A Lightweight Redis-like Key-Value Store in Go

Check it out on GitHub

yeeKV is a lightweight Redis-inspired key-value store, perfect for learning and experimentation. It supports core Redis features like strings, lists, and streams, and ensures thread-safe operations, so multiple clients can safely interact with the store concurrently. While it already works well, there’s still plenty of room for more features.

Features

• RESP Protocol: Works with Redis clients
• Multiple Data Structures: Strings, Lists, Streams
• Key Expiration: Millisecond precision (PX)
• Thread-Safe: Concurrent access is safe

Quick Start

Start the server:

go build -o yeekv main.go
./yeekv

Use the built-in CLI:

go build -o yeekv-cli cli.go
./yeekv-cli

Example session:

yeeKV> SET foo bar
OK
yeeKV> GET foo
bar
yeeKV> exit
bye~

Roadmap

• More Redis commands (DEL, EXPIRE, INCR…)
• Optimized storage & memory management
• Persistence (RDB / AOF)
• Cluster mode & Pub/Sub support
