go-opentracing-example

End-to-end go opentracing example using jaeger as tracer.

This example shows how to leverage open tracing to see a span that covers the following flow:

As you can see:

• a span is started by performing an HTTP request to the http-sever-initiator that calls http-sever-receiver over HTTP in turn
• http-sever-receiver calls grpc-server over GRPC after having registered a child span
• grpc-server publishes a message into kafka and returns a successful response upstream after having registered a child span
• kafka-consumer consumes the message from the todos topic and creates a new record in the todos table. It creates two spans: one for the time spent in the whole consumer logic and one for the time spent during the database query.

How to run

You can run the project using docker-compose up (tbd)

TODOS

• Write solid documentation.
