Covers how optimistic concurrency control (OCC) works and why it requires retry logic, primary key strategies (UUIDs vs. identity columns vs. hybrid patterns), schema design to minimize hot-row contention, transaction best practices, idempotency patterns, error classification, schema migration with the expand-contract pattern, and observability metrics. Uses a multi-Region social application as a running example throughout. ## Full article daily.dev links to this article rather than hosting it.
