SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you design and implement event stores for event-sourced systems, replacing ad hoc persistence with a clear, reliable event storage strategy.

Core Features & Use Cases

  • Event Store Architecture: Plan append-only streams, global ordering, and optimistic concurrency for durable event persistence.
  • Technology Selection: Compare EventStoreDB, PostgreSQL, Kafka, DynamoDB, and Marten to match the right storage approach to your stack.
  • Practical Implementation: Use ready-made schema and code templates for stream reads, global reads, subscriptions, checkpoints, and idempotent writes.
  • Use Case: A backend team can use this Skill to design a production-ready event store for an order management system and define how events are written, queried, and replayed.

Quick Start

Ask the assistant to design an event store for your event-sourced application and recommend the best storage model, schema, and concurrency strategy.

FAQPage Schema
How do I design an event store for an event-sourced backend?

Design an event store by planning append-only streams, global ordering, and optimistic concurrency for durable event persistence. This establishes a reliable infrastructure strategy for writing, querying, and replaying application state changes.

What is the best way to ensure idempotent writes and handle concurrency in event sourcing?

Handle concurrency in event sourcing by enforcing optimistic concurrency controls and requiring idempotent writes. This guarantees that append-only event streams remain durable and consistent during stream and global reads.

How does event store technology selection compare between PostgreSQL, Kafka, and DynamoDB?

Technology selection compares EventStoreDB, PostgreSQL, Kafka, DynamoDB, and Marten to match the right storage approach to your stack. Comparing these options ensures your event store meets specific infrastructure planning and query requirements.

Can I use this event store design approach for subscription processing and checkpoints?

Yes, you can use this event store design for subscription processing and checkpoints. It provides ready-made schema and code templates that define how events are written, queried, and replayed for application backends.

When do I need an append-only event store with global ordering for my application?

You need an append-only event store with global ordering when building event-sourced systems that require durable event persistence. This approach supports infrastructure planning by ensuring reliable stream reads and global reads.

What schema design is needed for event store streams and global reads?

Schema design for event store streams and global reads requires templates for append-only ordering, optimistic concurrency, and idempotent writes. This schema defines how events are structured, queried, and replayed across the application backend.
