THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

The same trace will be looking pretty similar using traditional Zipkin UI frontend:
Example #4: Client and Server with binary annotations (key/value)
In this example server-side implementation of the JAX-RS service is going to add key/value annotations to the active span. The client-side code stays unchanged.

The actual invocation of the request by the client (with service name tracer-client) and consequent invocation of the service on the server side (service name tracer-server) is going to generate the following sample server trace properties (taken from Jaeger UI):
The same trace will be looking pretty similar using traditional Zipkin UI frontend:
Example #5: Client and Server with parallel trace (involving thread pools)
In this example server-side implementation of the JAX-RS service is going to offload some work into thread pool and then return the response to the client, simulating parallel execution. The client-side code stays unchanged.
