<p>In <a class="issue-link js-issue-link" data-error-text="Failed to load issue title" data-id="321490578" data-permission-text="Issue title is private" data-url="https://github.com/openstreetmap/openstreetmap-website/issues/1852" data-hovercard-type="issue" data-hovercard-url="/openstreetmap/openstreetmap-website/issues/1852/hovercard" href="https://github.com/openstreetmap/openstreetmap-website/issues/1852">#1852</a> we're looking at processing GPX files using the <a href="https://edgeguides.rubyonrails.org/active_job_basics.html" rel="nofollow">Active Job</a> framework, and there's many other places where it makes sense to start using job queues too (for example, sending multiple diary entry comment notifications) for tasks that could be run asynchronously.</p>
<p>ActiveJob comes with a simple built-in task runner, but that uses the current process and so isn't really production-grade. I've had good experiences with <a href="https://github.com/collectiveidea/delayed_job">Delayed Job</a>, which stores jobs in PostgreSQL. The alternative would be e.g. resque using redis for job persistence, but I don't think that's necessary since it's something else to run, and we're not exactly creating bazillions of jobs per second.</p>
<p>Since I'm fairly confident that we'll use Active Job for multiple topics, I think it's worth setting up the backend (migrations, configuration and deploying task runners in production) separately, to avoid having to combine all this stuff into a larger PR.</p>
