Queue-Based Load Leveling
Use a queue to create a buffer between a task and a service
Intent & Description
The Queue-Based Load Leveling pattern uses a queue that creates a buffer between a task and a service to smooth intermittent heavy loads. The task queues requests, and the service processes them at a steady pace. This prevents the service from being overwhelmed by bursts of requests.
Real-world Use Case
Use when your application experiences variable load patterns or when you need to protect a service from overload.
