SRPC is an enterprise-level RPC system used by almost all online services in Sogou. It handles tens of billions of requests every day, covering searches, recommendations, advertising system, and other types of services.
Bases on Sogou C++ Workflow, it is an excellent choice for high-performance, low-latency, lightweight RPC systems. Contains AOP aspect-oriented modules that can report Metrics and Trace to a variety of cloud-native systems, such as OpenTelemetry, etc.
Its main features include:
SRPC, bRPC, Thrift, tRPC
Linux, MacOS, Windows
Protobuf, Thrift
Json, Protobuf, Thrift Binary
gzip, zlib, snappy, lz4
tcp, udp, sctp, tcp ssl
srpc has been packaged for Debian and Fedora. Therefore, we can install it from source code or from the package in the system.
reference: Linux, MacOS, Windows Installation and Compilation Guide
Let's quickly learn how to use it in a few steps.
For more detailed usage, please refer to Documents and Tutorial.
syntax = "proto3";// You can use either proto2 or proto3. Both are supported by srpc
message EchoRequest {
string message = 1;
string name = 2;
};
message EchoResponse {
string message = 1;
};
service Example {
rpc Echo(EchoRequest) returns (EchoResponse);
};

});

}
These compile commands are only for Linux system. On other system, complete cmake in tutorial is recommanded.
g++ -o server server.cc example.pb.cc -std=c++11 -lsrpc
g++ -o client client.cc example.pb.cc -std=c++11 -lsrpc
Terminal 1:
./server
Terminal 2:
./client
We can also use CURL to post Http request:
curl 127.0.0.1:8811/Example/Echo -H 'Content-Type: application/json' -d '{message:"from curl",name:"CURL"}'
Output of Terminal 1:
get_req:
message: "Hello, srpc!"
name: "workflow"
set_resp:
message: "Hi, workflow"
get_req:
message: "from curl"
name: "CURL"
set_resp:
message: "Hi, CURL"
Output of Terminal 2:
message: "Hi, workflow"
Output of CURL:
{"message":"Hi, CURL"}
