thriftproxy

This is a golang implemented proxy for thrift binary protocol over TCP/IP. The following picture shows the architecture of this thrift proxy:

The client connects to the thrift proxy and thrift proxy will connect to backend thrift servers. The request to to the thrift proxy will be dispatched to backend servers in round-robin way.

How to compile it

Download golang 1.14+, set your GOROOT and your GOPATH for the thriftproxy properly, like:

# cd ~
# wget https://dl.google.com/go/go1.14.1.linux-amd64.tar.gz
# tar -zxvf go1.14.1.linux-amd64.tar.gz
# export GOROOT=$HOME/go
# export PATH=$GOROOT/bin:$PATH
# mkdir ~/thriftproxy
# export GOPATH=~/thriftproxy
# go get -u github.com/ochinchina/thriftproxy

After executing above commands under linux, the thriftproxy binary will be available in the ~/thriftproxy/bin directory.

Start the thriftproxy

Before starting the thriftproxy, you need to prepare a configuration file for thriftproxy. The sample configuration file test-proxy.yaml can be found in the git. After preparing the configuration file, you can start the thriftproxy with flag "-c" like:

# cat test-proxy.yaml
admin:
  addr: ":7890"
proxies:
  - name: test-1
    listen: ":9090"
    backends:
      - addr: "127.0.0.1:9091"
        readiness:
          protocol: tcp
          port: 7890
      - addr: "127.0.0.1:9092"
        readiness:
          protocol: tcp
          port: 7891
  - name: test-2
    listen: ":9020"
    backends:
      - addr: "127.0.0.1:9022"
      - addr: "127.0.0.1:9021"

  - name: test-3
    listen: ":9030"
    backends:
      - addr: "127.0.0.1:9032"
      - addr: "127.0.0.1:9031"
# ~/thriftproxy/bin/thriftproxy -c test-proxy.yaml

rest API for adding/removing backend

The thriftproxy will listen on the admin address to accept the restful call to add/remove backend servers. In the above test-proxy.yaml example, the admin address is ":7890" which means it will listen on port 7890 in all network ip address.

# cat backends.yaml
proxies:
  - name: test-1
    backends:
      - addr: "127.0.0.1:6666",
        readiness:
          protocol: http
          port: 7893
          path: /healthz
      - addr: "127.0.0.1:6667",
        readiness:
          protocol: tcp
          port: 7894          
# curl http://localhost:7890/addbackend -d@backends.yaml
# curl http://localhost:7890/removebackend -d@backends.yaml
