Asynchronous Task Queues

lthough our user facing site is the most visible part of what we do, it’s only half the story. Cayman Islands WhatsApp Number List. The other half takes part in asychronous queues, which work overtime behind the scenes, and process hundreds of millions of tasks each year. In this post I’ll explain a bit about why we use queueing at 99designs, and how it all works. A Bit of Background — If you’ve never heard of asynchronous task queues before, the idea behind them is pretty simple. Say you had a task you needed to do such as buying some milk but you didn’t have the time to take care of it yourself, so instead you leave a note for a

Why We Use Queues — Now obviously our web apps aren’t busy ordering milk, more common uses for a queue are things like talking to third party API’s, sending emails, or performing computationally expensive tasks like image resizing. But why do we need a queue at all? Wouldn’t it be easier to just do the work a user requires immediately? Well, there’s a few reasons: The first reason is speed: When we’re talking to a third party API we have to face reality; unless that third party is physically located next to our infrastructure,

All it would take is the addition of a few API calls and we could easily end up doubling or tripling our response time, leading to a sluggish site and unhappy users. However if we push these API calls into our queue instead, we can return a response to our users immediately while our queues take as long as they like to talk to the API. The second reason is reliability: We don’t live in a world of 100% uptime, services do go down, and when they do it’s important that our users aren’t the ones that suffer. If we were to make our API calls directly in the users requests we wouldn’t have any good options in the event of a failure.
