Event Store Design

Gets you from zero to production event store with PostgreSQL schemas, Python implementations, and all the infrastructure decisions sorted. Covers stream versioning, optimistic concurrency, subscription checkpoints, and the inevitable snapshot table you'll need later. Handles the tricky bits like global positioning and duplicate event detection that everyone gets wrong initially. Compare EventStoreDB vs Kafka vs DynamoDB with honest limitations instead of marketing fluff. Good for when you need event sourcing but can't justify another database, or when you're building custom event infrastructure and need the boilerplate done right.
