Show HN: Light implementation of Event Sourcing using PostgreSQL as event store
This reminds me of Commanded[0] for elixir which also uses Postgresql by default.

Adding soft delete to a Phoenix Commanded (CQRS) API
So, I lied told a half-truth about aggregates. They are not hydrated in-memory for every command / event. In reality, aggregates are implemented with GenServer each caching their state and being managed under the commanded application's supervision tree (ultimately by a DynamicSupervisor called Commanded.Aggregates.Supervisor, to be specific).

Using CQRS in a simple Phoenix API with Commanded
The Commanded hex package is a fabulous CQRS library used by some real companies in production, but it doesn't have a great on-ramp.

Phoenix LiveView, but event-sourced
The context: I'm building a cryptocurrency exchange application. I don't have the business chops to run an actual exchange, so this is just for fun. The application is built in Elixir, using the Commanded framework for CQRS/ES goodness, and Phoenix LiveView because it's the hot new thing that I wanted to learn.

OOP vs. services for organizing business logic: is there a third way?

Event Store with Rails
Co-author of the Sequent gem (https://www.sequent.io) here. Can confirm that it’s a great gem to build event sourced applications with (as long as you’re using PostgreSQL). It’s very battle tested as it has been extracted from/used in a web based accounting system that currently holds about 1 billion events in the event store.

Using CQRS in a simple Phoenix API with Commanded
I have been curious about the concepts of event sourcing and CQRS for a while— obsessively reading books like Practical Microservices (Garofolo) and Architecture Patterns with Python (Percival, Gregory), along with documentation for libraries like Sequent (Ruby), Commanded (Elixir).
