Quick Reference
DynamoDB: Define access patterns FIRST, then design keys. Single table design for co-located data. PK+SK for hierarchical data. GSI for secondary access patterns (max 20). Prefix keys with entity type (USER#, ORDER#). Transactions for ACID across items (max 100 items, 4MB). Eventually consistent reads by default. 400KB item limit.
Use When
- DynamoDB data modeling
- Single table design
