SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps engineers design and implement robust event stores for event-sourced architectures, enabling durable persistence and predictable event history.

Core Features & Use Cases

Store selection & architecture: Evaluate candidate event stores (database-backed, log-based, or hybrid) and decide on streaming, snapshots, and versioning strategies.
Schema & contracts: Define per-stream schemas, event types, and evolution rules with backward-compatible changes.
Scalability & reliability: Design for high-throughput writes, causal ordering, and fault tolerance across multiple streams and subsystems.
Use Case: For an e-commerce domain, design an order stream with events like OrderCreated, OrderPaid, and OrderShipped, including snapshotting and projections.

Quick Start

Set up an initial event store plan for a sample Order domain, define a basic stream "ORDER-<uuid>", and append a few example events to validate schema and versioning.

FAQPage Schema

How do I design an event store for event-sourced architectures?▼

Design an event store by evaluating database-backed or log-based stores, defining per-stream schemas, enforcing append-only semantics, and planning snapshots and versioning strategies to ensure durable event persistence.

What is per-stream versioning in event sourcing?▼

Per-stream versioning tracks the sequence of events within an individual stream, ensuring predictable event history, enforcing causal ordering, and enabling consistent projections across multiple streams and domains.

How do I handle schema evolution and backward-compatible changes in an event store?▼

Handle schema evolution by defining clear event contracts and per-stream schemas with explicit evolution rules that enforce backward-compatible changes, ensuring reliable event querying without breaking existing projections.

What's the best way to scale event store writes for high-throughput domains?▼

Scale event store writes by designing for high-throughput persistence across multiple streams and subsystems, utilizing hybrid or log-based stores with snapshotting to maintain fault tolerance and causal ordering.

When do I need snapshots in an event-sourced application?▼

You need snapshots in an event-sourced application to optimize projection rebuilding and state recovery, reducing the overhead of replaying long event streams while maintaining reliable event querying and append-only semantics.
