Example
For example, if you are sending an email to a customer after starting a task, it's best to immediately redirect the user to the next page while queuing the email to be sent in the background. This will speed up the load time for the next page, since sending an email can sometimes take several seconds or longer.
Another example would be updating an inventory system after a customer checks out with their order. Rather than waiting for the API calls to complete, which may take several seconds, you can immediately redirect user to the checkout success page while queuing the API calls to happen in the background.
