100 requests/minute

Suddenly:

10,000 requests

Without queue:

10,000 requests
  ↓
Mule
  ↓
Salesforce

You may overwhelm Salesforce.

With queue:

10,000 requests
      ↓
    Queue
      ↓
workers consume at controlled rate

buffering
backpressure
load leveling

Very useful integration vocabulary.
