Queue-Based Load Leveling pattern

Why and When?

Sometimes a part of our application just can not run that fast, it could be for example, avatar processing, email sending, and in these case we don't usually need a response/confirmation that the action is finished, we can push these tasks into queue and handle them asynchronously to take the load off the system.

How?

• push slow tasks into queue
• consume queue with worker
• many workers can run at the same time, so tasks are finished faster
