Database
Amazon DocumentDB
Amazon DocumentDB is a managed document database with MongoDB-compatible APIs for JSON-like application data. It can persist flexible agent state, prompt metadata, or model results when document access patterns dominate.
Key points
- Storage and compute scale independently within service limits
- Clusters replicate data across Availability Zones
- MongoDB compatibility is API-focused and must be verified for required features and versions
When to use it
- Persist evolving agent session documents
- Store nested evaluation results and annotations
Exam tips
- Choose DocumentDB for document-shaped operational data, not automatically for vector retrieval
- Test driver and operator compatibility before migrating an existing MongoDB workload
