Redis Server Implementation in Rust

This project offers a streamlined implementation of a Redis server. Built with the power of Rust. Originally port of : Valinor Vault

Features

RESP (Redis Serialization Protocol) Specification

We've adopted the official RESP to ensure seamless communication in our system.

Core Commands

  • GET: Fetch the associated value of a given key.
  • SET: Assign a specific value to a key.
  • DEL: Erase a key and its corresponding value.
  • EXISTS: Verify the presence of a key in the system.
  • INCR: Increment the integer value of a key by 1.
  • DECR: Decrement the integer value of a key by 1.

List Operations

  • LPUSH: Add one or more values to the beginning of a list.
  • RPUSH: Add one or more values to the end of a list.
  • LRANGE: Retrieve a subset of the list stored at a key.

Expiration Commands

  • EX: Assign a key's time-to-live in seconds.
  • PX: Designate a key's time-to-live in milliseconds.
  • EXAT: Pinpoint an exact expiration timestamp for a key in seconds.
  • PXAT: Pinpoint an exact expiration timestamp for a key in milliseconds.

Little Sketch

We've included a diagram below to offer a clearer perspective on this implementation. This visualization should help elucidate the inner workings and flow of our Redis server replica.

Redis Flow

Benchmarks

This is the rust version of Redis server:

redis-benchmark -t set,get, -n 100000 -q
SET: 133155.80 requests per second, p50=0.191 msec
GET: 130890.05 requests per second, p50=0.183 msec

Actual Redis:

redis-benchmark -t set,get, -n 100000 -q
SET: 168634.06 requests per second, p50=0.159 msec
GET: 180180.17 requests per second, p50=0.151 msec
