have also used/introduced this to several places I've worked and it's been great each time. My only qualm is it's not particularly easy to modify the exponential back off timing without hacky solutions. Have you ever found a good way to do that?
The font this is based is based on Nunito, by Vernon Adams (as the article states). He's responsible for many google fonts and other open source fonts which rack up billions of views every year. I just wanted to share his story:
SELECT graphile_worker.add_job( 'send_email', json_build_object( 'to', '[email protected]', 'subject', 'graphile-worker test' ) );
(can also use the PERFORM statement instead of SELECT)
