SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides comprehensive guidance and practical templates for designing and implementing event stores, crucial for building scalable and maintainable event-sourced systems.

Core Features & Use Cases

  • Event Store Architecture: Understand the fundamental components and flow of an event store.
  • Technology Comparison: Evaluate different technologies like EventStoreDB, PostgreSQL, Kafka, DynamoDB, and Marten for suitability.
  • Implementation Templates: Get ready-to-use SQL schemas for PostgreSQL and Python code examples for building event stores.
  • Use Case: When architecting a new microservice that requires a reliable audit trail and the ability to reconstruct application state from historical events, this Skill will guide you through choosing the right technology and setting up the persistence layer.

Quick Start

Use the event-store-design skill to generate a PostgreSQL schema for an event store.

Frequently Asked Questions about event-store-design

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design an event store for a CQRS and DDD architecture?▼

Designing an event store for CQRS and DDD involves creating an append-only, ordered, and versioned persistence layer to capture domain events, enabling state reconstruction from historical records.

How do I implement event sourcing using PostgreSQL and Python?▼

Implement event sourcing with PostgreSQL and Python by deploying ready-to-use SQL schemas for append-only event storage and Python code templates that handle event persistence and state recovery.

What is the best database for building an event store?▼

The best database for an event store depends on your use case; comparing PostgreSQL, EventStoreDB, Kafka, DynamoDB, and Marten helps evaluate suitability for ordered, versioned, and append-only event storage requirements.

Can I use PostgreSQL as an event store for a microservice requiring an audit trail?▼

Yes, PostgreSQL works as an event store for microservices by utilizing provided SQL schema templates to establish append-only, ordered, and versioned event storage that ensures a reliable audit trail.

What are the key requirements for event store architecture?▼

Key requirements for event store architecture include enforcing append-only writes, maintaining strict event ordering, and tracking event versions to reliably reconstruct state and maintain auditability.

When should I not use PostgreSQL for event sourcing?▼

You should evaluate alternatives to PostgreSQL for event sourcing when your system requires specialized streaming capabilities or high-throughput event handling that exceeds standard relational database boundaries.
