SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Event-sourced architectures rely on correctly designed event stores to ensure immutability, traceability, and scalable state reconstruction. This guide explains how to choose a store, structure streams, and manage versions and snapshots to support reliable auditing and recovery.

Core Features & Use Cases

  • Guidance on selecting event store technologies (EventStoreDB, PostgreSQL, DynamoDB, etc.), storage schemas, and persistence patterns.
  • Patterns for per-stream versioning, global timelines, and snapshots to enable reliable replay and audit.
  • Practical templates and reference architectures for common event-sourced scenarios such as CQRS, auditing, and state reconstruction.

Quick Start

Outline your event store design for a new project and generate initial schemas and templates.

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

To design an event store, you must structure append-only storage, define stream schemas, and implement versioning. This ensures immutability, reliable state reconstruction, and scalable auditing for your event-sourced architecture.

What is the best way to manage versioning and snapshots in an event store?▼

Managing snapshots and versioning in an event store requires implementing per-stream versioning and global timelines. These patterns enable reliable state reconstruction and efficient replay without reprocessing entire event histories.

Can I use PostgreSQL or DynamoDB as an event store for CQRS architectures?▼

Yes, you can use PostgreSQL or DynamoDB as an event store. This approach provides specific schema design and persistence patterns to support CQRS, auditing, and state reconstruction across various domains.

How does append-only storage work in event sourcing?▼

Append-only storage in event sourcing works by strictly immutably recording state changes as a sequence of events. This guarantees traceability and supports consistency checks for reliable system recovery and auditing.

When do I need subscriptions and consistency checks in an event store?▼

You need subscriptions and consistency checks in an event store when building reliable event-sourced applications. They ensure accurate state synchronization across distributed components and maintain data integrity during concurrent operations.
