Background

Java app always need to call another java app,now we can use rmi/hessian etc. to realize,but they're not fast enough,so many of us select mina/netty or other high performance network framework to realize,every time when we change io framework,we need realize the rpc framework again,it's so boring....

Features

Current

This project abstract the high performance rpc framework,provide some basic implemenation:

• client proxy,so u can call remote just like call local: UserService.getById(id);
• server reflection,so u can intergrate the rpc framework with difference server implemenation,such as spring;
• server direct call,u can implement a specify interface to provide for client call;
• single or multi connections,in most case,single connection is enough,but in some cases,u'll need multi connections;
• connection reuse,so u don't need block user thread to wait for connection;
• synchronize call,rpc always need synchronize call;
• timeout,u cann't wait for server return response forever,so u need timeout policy,especially for online app;
• multi or custom serialize protocol(java/hessian/protobuf);
• custom your protocol.

Future

1. intergrate more network frameworks,such as thrift/avro;
2. intergrate with aio;
3. test coroutine version,maybe scala or kilim;
4. server can use different threadpools to handle requests;
5. support async call & group calls;
6. add connection protect,avoid create connection again and again;

QuickStart

For Users

• if u just want to use current mina/netty/grizzly/aio framework,pls see here.

For Developers

• if u want to custom serialize/deserialize,custom protocol,implement with other io framework or beat the benchmark record,pls see here;

Benchmark

Current benchmark record (single connection,100 concurrents,100 byte request,100 byte response) created by

grizzly-rpc with protobuf

let's beat the rpc benchmark record together!

we hope someone can help us to improve performance or implement your own rpc framework with your favorite io framework to beat the performance record. Benchmark Machine:

• CPU: E5620 (8 core HT 16 core)
• Memory: 24G
• Network: 1000Mb

• 100 concurrents,Single connection,Direct Call

• 100 concurrents,Single connection,Reflection Call

• Different Concurrents,Direct Call

• Different Concurrents,Reflection Call

• Different connections
