SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Event Store Design provides guidance for designing and implementing event stores for event-sourced systems, enabling durable persistence, replayability, and auditability of domain events.

Core Features & Use Cases

  • Architecture decisions for event stores, including stream design, versioning, global position tracking, and snapshots
  • Technology comparison and selection across backends such as PostgreSQL, EventStoreDB, DynamoDB, Kafka, and Marten
  • Practical templates and patterns for schemas, events, subscriptions, and checkpoints
  • Best practices around immutability, idempotent writes, optimistic concurrency, and event replay scenarios
  • Real-world use cases: building an order system with event-sourced writes, auditing, and event-driven integrations

Quick Start

Choose a backend (PostgreSQL, EventStoreDB, or DynamoDB) and scaffold a minimal event-store using the provided templates.

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 schema for event-sourced systems?▼

Design an event store by enforcing immutability, versioning, and stream design while applying practical templates for events, subscriptions, and checkpoints across your chosen backend for durable domain event persistence.

What is the best way to handle optimistic concurrency in an event store?▼

Handle optimistic concurrency in an event store by applying idempotent writes and versioning best practices, ensuring durable event replayability and preventing write conflicts during concurrent domain event operations.

Can I use PostgreSQL and DynamoDB as backends for event sourcing?▼

Yes, you can use PostgreSQL and DynamoDB as event sourcing backends. The skill provides technology comparisons and selection criteria across PostgreSQL, EventStoreDB, DynamoDB, Kafka, and Marten to fit your architecture.

How do I implement real-time subscriptions and event replay in an event store?▼

Implement real-time subscriptions and event replay by utilizing provided schema templates and global position tracking, enabling auditability and downstream event-driven integrations for your domain events.

When should I use snapshots in event store architecture?▼

Use snapshots in event store architecture when you need to optimize performance during event replay, reducing the overhead of loading long event streams while maintaining auditability and immutability.
