This repository holds a minimalistic example of a gRPC long lived streaming application.
To learn more, visit the blog post: https://dev.bitolog.com/grpc-long-lived-streaming/
To compile the proto file, run the following command from the protos folder:
$ protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative longlived.proto
Note that this was tested on protoc version: libprotoc 3.6.1
Navigate to /server folder and run the following:
$ go build server.go
$ ./server
2021/03/04 08:48:09 Starting server on address 127.0.0.1:7070
2021/03/04 08:48:09 Starting data generation
The client process emulates several clients (default is 10).
Once the server is up, navigate to /client and run the following:
$ go build client.go
$ ./client
