drpc
Drpc - Correct, high performance, robust, easy use Remote invocation framework
drpc
- Super high performance, double performance(qps) as fast as Tarpc (Google)
- based T-L-V.for example:
[Tag][Length][Value] - support Custom Serialization crate. for example: bincode,json,bson...any serde Serialization
- support Load Balance.(Round/Random/Hash/MinConnect)
- support Custom registry, microservices. see redis_registry
- support tokio，this is async/await crate
- zero overhead, Accept/Response only serialize the once and deserialization once
T-L-V layout
// Frame layout
// id(u64) + ok(u8) + len(u64) + payload([u8; len])
// request frame layout. payload = method([u8;len])+'\n'(u8)+arg_data([u8;len])
// id(u64) + ok(u8) + len(u64) + payload([u8; len])
// response frame layout.ok=0? payload = error string,ok=1? payload = data
// id(u64) + ok(u8) + len(u64) + payload ([u8; len])
// Header Length layout
// head(8(id)+1(ok)+8(length)=17)
qps benchmark- remote_method(i32)->i32
| Framework | Platform(1-server-1-client) | ns/operation（lower is better） | Qps(higher is better) |
|---|---|---|---|
| drpc/tokio | AMD 5950x-16 CPU, 32G mem | 49213 ns/op | 20317 QPS/s |
| tarpc/tokio | AMD 5950x-16 CPU, 32G mem | 105644 ns/op | 9465 QPS/s |
how to use?
tokio = { version = "1", features = ["full"] }
dark-std = "0.1"
drpc = "0.1"
- client
>>>>>>>>>>>>> :{}", resp);">
use drpc::client::Client; use drpc::codec::BinCodec; let c = Client::<BinCodec>::dial("127.0.0.1:10000").await.unwrap(); let resp:i32 = c.call("handle", 1).await.unwrap(); println!("resp=>>>>>>>>>>>>>> :{}", resp);
- server
use drpc::server::Server;
use drpc::Result;
use drpc::codec::BinCodec;
async fn handle(req: i32) -> Result<i32> {
Ok(req)
}
let mut s = Server::<BinCodec>::new();
s.register_fn("handle", handle);
s.register_fn("handle2", | arg:i32| async move{
Ok(arg + 1)
});
s.serve("0.0.0.0:10000").await;
