README

qproxy

qproxy is a single frontend API for multiple backend queueing systems. It supports gRPC as well as http/json via the gRPC-Gateway. For multi-cloud environments, or environments with multiple queueing systems, qproxy provides a unified interface and a single place for metrics, rate limiting, etc.

qproxy currently supports SQS as a backend, with plans to add GCP's PubSub.

Building

You will need to follow this to install protoc . Once that's done you should be able to run "make" to build the project.

Running

./build/qproxy.linux --region=us-west-2

Functions

func AddRoutes

func AddRoutes(mux *http.ServeMux, server *QProxyServer) error

AddRoutes matches a mux with handlers

Types

type CompressionHandler

type CompressionHandler struct {
	Handler func(http.ResponseWriter, *http.Request)
}

CompressionHandler is a wrapper around http.Handler which adds suitable response compression based on the client's Accept-Encoding headers.

func (CompressionHandler) ServeHTTP

func (c CompressionHandler) ServeHTTP(writer http.ResponseWriter, req *http.Request)

ServeHTTP adds compression to the original http.Handler's ServeHTTP() method.

type ListQueuesServerStream

type ListQueuesServerStream struct {
	rpc.QProxy_ListQueuesServer
	NewCtx context.Context
}

func (ListQueuesServerStream) Context

func (x ListQueuesServerStream) Context() context.Context

type QProxyServer

type QProxyServer struct {
	// contains filtered or unexported fields
}
