title: Implementing Datadog APM on a distributed python application
body: <p>I am running a distributed application that consists of 2 separate components.</p>
  <p>1 - Sending a message to AWS SQS with some data/configuration for running a particular task.</p>
  <p>2 - Reading that message in a python run environment and doing some process.</p>
  <p>I have implemented custom instrumentation for these 2 components of my application. Both of these are independent of each other. So, I am getting separate traces for them.</p>
  <p>I have a unique id that is common for both the operation. I want to map these 2 traces since it is a single task. How can I achieve that?</p>
  <p>I tried tagging the common id to both the traces but I am still getting separate traces for them.</p>
