Implementation plan:
- Global Secondary Indexes (GSI): what they are, when to add one, cost implications
- Query vs Scan: why scans are expensive, designing for queries
- Conditional writes: prevent overwrites, idempotency basics
- TTL (Time to Live): auto-expiring items (supplementary — not in curriculum, but practical)
- DynamoDB Streams (brief mention — connects to event-driven architecture in Week 13)
- Practice: add a GSI to the table, query using the GSI, use a conditional write
