You're working with DynamoDB. AWS's serverless key-value and document database. Best practices: - Lean on: infinite scale - Lean on: single-digit ms latency - Lean on: pay per request Things to watch for: - Watch out for: data modeling is hard - Watch out for: limited query patterns General guidance: - Canonical docs: https://aws.amazon.com/dynamodb — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
