 [Chaining](https://laravel.com/docs/9.x/queues#job-chaining) is a workflow design pattern that involves the sequential execution of a series of activities, with the output of one activity potentially serving as the input to the next activity in the chain. This pattern is often used to create a linear, step-by-step process for completing a task.

 In contrast, the fan-out/fan-in pattern involves dividing a task into smaller sub-tasks and then combining the results of those sub-tasks to produce the final result. This pattern is often used to parallelize a task and improve its performance by leveraging the power of multiple queue workers.
