SQL Maxis: Why We Ditched RabbitMQ And Replaced It With A Postgres Queue
We recently ripped out RabbitMQ from our system and replaced it with a queue built on top of our Postgres db and written in SQL.

This is a writeup of that change, the rationale behind it, and how we did it. Note: this is not a
