NATS Streaming via gRPC Prototype

Prototype to try out NATS Streaming via a gRPC service, using streaming request/response for publishing and subscribing to the messages.

Usage

Build the docker image and run the server.

docker-compose build
docker-compose up nats server

Run two terminals, one for publishing messages,

docker-compose up publisher

And another for subscribing to the messages.

docker-compose up subscriber

To get metrics, visit http://localhost:9000/metrics.

E.g. Watch for any metric with the eventinator prefix

watch 'curl http://localhost:9000/metrics | grep ^eventinator'

Hacking

On Linux, install the protoc tool and the golang compilers for protobuf and grpc compilers if you plan on changing any of the *.proto files.

sudo apt install protobuf-compiler
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

To (re)generate the protocol buffers and gRPC files.

go generate
