# redistributed

Library to support propagation of distributed tracing information for applications communicating over Redis channels.

## Requirements

* docker

* docker-compose

## Run example

```bash

git clone https://github.com/codeboten/redistributed.git

cd redistributed

docker-compose up

curl localhost:5000

open http://localhost:16686

```

## Usage

```go

import "github.com/codeboten/redistributed/propagation"

func publishMessage(w http.ResponseWriter, r *http.Request) {

	span := trace.FromContext(r.Context())

	conn := redisPool.GetWithContext(r.Context()).(redis.ConnWithContext)

	publishCtx, publishSpan := trace.StartSpan(r.Context(), "publish")

	_, err := conn.DoContext(publishCtx, "PUBLISH", "mychannel1", redispropagation.Binary(publishSpan.SpanContext(), "message"))

}

func receiveMessage(ctx context.Context) {

	pubsub := client.Subscribe("mychannel1")

	ch := pubsub.Channel()

	for msg := range ch {

		spanContext, message, ok := redispropagation.FromBinary(payload)

		if ok {

			_, span := trace.StartSpanWithRemoteParent(ctx, "generateReport", spanContext)

		}

		fmt.Printf("Message received:%s", message)

	}

}

```
