## 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.


## Use Cases
Use when your application experiences variable load patterns or when you need to protect a service from overload.





## Trade-offs


### Advantages

- Smooths out load variations

- Protects services from overload

- Enables steady resource utilization

- Improved reliability under heavy load




### Considerations & Drawbacks

- Queue infrastructure required

- Potential latency for queued items

- Backpressure management needed
