Red is a toy implementation of Redis in Rust.
To start the server:
cargo run --releaseThen 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
Currently implemented commands:
SETGETDELPING
The server is single-threaded and handles commands sequentially. Data is stored in memory in a HashMap.
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. 🤯
