HOW I SOLVED A DISTRIBUTED QUEUE PROBLEM AFTER 15 YEARS

Summary from the TLDR Web Dev newsletter

Jeremy Edberg, formerly responsible for Reddit's infrastructure, discusses the challenges and limitations of traditional task queues using RabbitMQ for operations like Reddit's vote processing. While they do have scalability and flow control benefits, they are also fragile and have the potential for data loss due to queue failures. A better solution is durable queues that checkpoint task status to a persistent store like Postgres, as this can enable the resumption of failed jobs and prevent data loss.
