RailsConf 2022 - Call me back, Postgres by Ifat Ribon

Rails' Active Record callbacks provide a simple interface for executing a process when something happens to a database record. However, sometimes Active Record callbacks aren’t the best solution available. For those cases, this talk introduces a great alternative: Postgres' trigger functionality, a way of implementing callbacks at the database level. Coupled with Postgres' listen and notify features, you can develop creative solutions for making your Rails app the center of an otherwise complex system, managing data syncing and other processes seamlessly, regardless of consumers of the app.
