SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides comprehensive guidance on designing and implementing event stores, crucial for building scalable and resilient 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, and DynamoDB for their suitability.
  • Implementation Templates: Provides practical SQL and Python templates for building event stores.
  • Use Case: When architecting a new microservice that requires event sourcing, use this Skill to understand the best practices for designing its event store, choosing the right technology, and implementing the core persistence logic.

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 an event-sourced system?▼

Design an event store by structuring append-only, ordered, and versioned event persistence. This skill provides architecture guidance, technology selection criteria, and implementation templates for building robust event sourcing infrastructure.

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

Choosing the best database for an event store requires comparing EventStoreDB, PostgreSQL, Kafka, and DynamoDB. This skill provides a technology comparison to evaluate their suitability for append-only, ordered, and versioned event persistence.

How do I create an event store schema in PostgreSQL?▼

Create an event store schema in PostgreSQL using provided SQL templates. This skill guides the implementation of append-only, ordered, and versioned event persistence logic specifically tailored for PostgreSQL databases.

Can I use DynamoDB or Python for event sourcing infrastructure?▼

Yes, you can use DynamoDB or Python for event sourcing infrastructure. This skill provides implementation templates for both technologies, addressing challenges in building event stores and optimizing event storage within distributed systems.

When should I use a dedicated event store database versus a relational database?▼

Deciding between a dedicated event store database and a relational database depends on your architecture needs. This skill compares technologies like EventStoreDB and PostgreSQL to determine the best fit for your event-sourced systems.
