An event store library for Elixir that uses PostgreSQL as its underlying persistence engine. It supports appending and reading event streams, subscriptions, and running on a cluster of nodes.

Use cases

• implement event sourcing in an Elixir application
• store append-only event streams in PostgreSQL
• build a CQRS system with Elixir
• subscribe to events from an event stream
• run an event store across a cluster of nodes

When to choose

• you're building an Elixir app with event sourcing or CQRS
• you want to use PostgreSQL as your event store instead of a dedicated event store database
• you need persistent or transient subscriptions to event streams

When to avoid

• you're not using Elixir or the BEAM ecosystem
• you need a standalone event store server like EventStoreDB or Kafka
• your persistence model doesn't fit append-only event streams
