A Rust client/server library for Redis.
extern mod redis = "redis#0.1";
fn main() {
let mut redis = redis::Client::new("127.0.0.1:6379");
redis.set_int("counter", 1);
redis.set("key", "Hello");
redis.incr("counter");
let counter = redis.get_int("counter").unwrap();
println!("counter = {}", counter);
let key = redis.get_str("key").unwrap();
println!("key = {}", key);
match redis.get("key") {
redis::Nil => {
println!("Key not found")
}
redis::Data(ref s) => {
println!("{:?}", std::str::from_utf8(*s))
}
_ => { fail!() }
}
}For a simple redis server implementation which supports GET/SET commands see examples/server/main.rs.
I did some early performance benchmarks with rust-0.9 and compared it against redis-benchmark.
redis-benchmark -n 100000 -c 1 -t set # ~18500 reqs/sec
redis-benchmark -n 100000 -c 2 -t set # ~27000 reqs/sec
redis-benchmark -n 100000 -c 4 -t set # ~36000 reqs/sec
redis-benchmark -n 100000 -c 8 -t set # ~44000 reqs/sec
./bin/bench 1 100000 # ~19500 reqs/sec
./bin/bench 2 100000 # ~19100 reqs/sec
./bin/bench 4 100000 # ~18800 reqs/sec
./bin/bench 8 100000 # ~18000 reqs/sec
At this simple benchmark, rust-redis consistently shows about 18000 requests per second regardless of concurrency. I think this is because the way scheduling works. Using native threads would probably lead to the same performance as redis-benchmark.
