reredis

reredis is a reimplementation of Redis (server) in Rust programming language. The current equivalent version of Redis is 1.x - 2.x. It supports Linux and MacOS(it depends on Unix API like fork, so Windows version is not available now).

Licensed under BSD 3-Clause.

Building reredis

reredis can be compiled on all *nix systems that supports Rust toolchain(but tested only on Linux and MacOS).

It requires Rust(>= 1.37.0) to compile. To install Rust, see this.

The build command is

%cargo build --release

and the executable is located at ./target/release/reredis

After building Redis, it is a good idea to test it using:

%cargo test  # This is unit tests

and

%cargo test --test server_test -- --ignored --nocapture # This is integration tests

Alternatively, you can use the Makefile, which is just a wrapper of the former commands.

%make

to build.

%make test

to do all tests.

How to use?

The command is identical to Redis. Like

%reredis  # start on 127.0.0.1:6379

and

%reredis --bind 0.0.0.0 --port 9090 # binds on all ip address and port 9090

and

%reredis example.conf # configured by example.conf

Other supported configuration are listed here

Relation with Redis

reredis is a reimplementation of Redis, and its protocol is compatible with Redis Protocol(RESP). But the current version of .rdb file is not compatible with Redis, because the format of ziplist and intset is slightly different. I'm still working on it.

Clients

Since the protocal is compatible with Redis. All clients of Redis can be used with reredis, like redis-rs in Rust. There is currently on implementation of redis-cli in my project, but I'm working on it.
