Introduction

Rudis is a database written in Rust, multi-threaded, and compatible with redis. It has better performance than Redis and solves some common problems of Redis.

Goal (WIP)

  1. Compatible with redis client

  2. More efficient than redis

    • Implemented with rust, you can write a safer and more efficient multi-threaded data engine
    • Higher io efficiency
    • Optimized for big keys
    • Optimized for hot keys

  3. Less problems than redis

    • Use rust to reduce various memory security bugs
    • Timely clean up expired data

  4. Better operation and maintenance than redis

    • Easier to manage clusters
    • Random horizontal expansion
    • Automatic leader-follower switch
    • Automatic scheduling of hot slots

known issues, warnings

  • Disclaimer Please don't use rudis in production now.
  • If reliability is your primary constraint, use Redis. Rudis is beta.
  • The PD module has not been tested and is temporarily not highly available, so there may be a single point of failure problem
  • Only supports linux and macos

Quick start

  1. Prepare the latest version of rust toolchain
  2. Clone code
  3. Execute in sequence
    • cd rudis
    • cargo build --release
    • ./target/release/server (Specify address to start: RUDIS_server_addr=0.0.0.0:6379 ./target/release/server)

Current roadmap (Version 0.1)

  1. Pass Redis TCL test
  2. Complete high-availability pd

Benchmarks

The performance of Rudis is better than Redis 6.2.5. Check the details.
