🍣 Red

Red is a toy implementation of Redis in Rust.

🚀 Usage

To start the server:

cargo run --release

Then you can connect to it with the Redis CLI:

redis-cli

(Or, in a Docker container: docker run --rm -it redis:7.2-alpine redis-cli -h host.docker.internal.)

And run commands like:

SET foo bar
GET foo

🔡 Commands

Currently implemented commands:

• SET
• GET
• DEL
• PING

🏗 Architecture

The server is single-threaded and handles commands sequentially. Data is stored in memory in a HashMap.

⚡ Performance

Performance is not a goal of this project, but it's still interesting to see how it compares to Redis. In my very unscientific tests, Red seems on par with Redis. 🤯

% deno run --allow-net=127.0.0.1 --allow-run=lsof benchmark.ts
Benchmarking the following Redis instance:
