Event Store Design

About

Provides comprehensive guidance for designing and implementing event stores, the backbone of any event-sourced system. It covers essential architectural concepts like stream management and global ordering while offering concrete implementation templates for popular technologies including PostgreSQL, DynamoDB, and EventStoreDB. Whether building custom infrastructure from scratch or selecting a managed service, this skill helps ensure data immutability, handle optimistic concurrency, and optimize for both real-time subscriptions and long-term event archival.
