Does it support event subscriptions?

Yes, it includes patterns for implementing event subscriptions and tracking checkpoints so downstream consumers can process events reliably in real-time.

What is an event store?

An event store is a specialized database designed to store a sequence of immutable state-changing events, serving as the single source of truth in event-sourced systems.

Can I use PostgreSQL as an event store?

Yes, this skill includes optimized SQL schemas and Python implementation patterns specifically for using PostgreSQL as a reliable, versioned event store.

How does this skill handle concurrency?

It provides templates for optimistic concurrency control using stream versioning to ensure that multiple writers do not conflict or overwrite the stream state.

Database Management

Designs and implements robust, immutable event stores for event-sourced architectures and high-concurrency backend systems.

This skill provides a comprehensive framework for building the foundational storage layer of event-sourced systems. It guides developers through selecting the right technology—ranging from specialized databases like EventStoreDB to relational systems like PostgreSQL—while ensuring core requirements like append-only immutability, global ordering, and optimistic concurrency are met. With included templates for schema design, snapshotting, and implementation in Python and SQL, it helps developers create reliable audit trails and reactive infrastructures that scale.
