title: AWS Lambda CloudWatch log streams missing in action?
body: <p>From the what I've read, there is supposed to be a CW log stream per container.
  I have a system that calls hundreds of Lambda (same Lambda function) concurrently (via SNS).
  I only see 10-20 log streams each time. AFAIK it's supposed to be only one Lambda per container, so it doesn't add up.
  Anyone have an explanation?</p>
