AWS DynamoDB API
AWS DynamoDB is a fully managed NoSQL key-value and document database with single-digit millisecond latency at any scale — accessed via AWS SDK or DynamoDB REST API with IAM auth.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
IAM roles with table-level and attribute-level conditions. VPC endpoints for network isolation. Encryption at rest with AWS KMS. Point-in-time recovery (PITR) for compliance. FedRAMP High, HIPAA, PCI-DSS.
⚡ Reliability
Best When
Your agent needs fast, scalable NoSQL storage on AWS with automatic scaling, TTL, and Streams for event-driven workflows.
Avoid When
You need complex queries, relational data, or are not on AWS — DynamoDB's query model requires careful schema design upfront.
Use Cases
- • Storing agent state, session data, and task queues with automatic TTL expiration
- • High-throughput read/write workloads requiring low-latency NoSQL storage from agents
- • Event-driven agent workflows triggered by DynamoDB Streams on data changes
- • Global multi-region active-active data replication via DynamoDB Global Tables
- • Serverless backends where agents need schemaless, scalable document storage
Not For
- • Complex relational queries with joins, aggregations, or arbitrary SQL (use RDS or Redshift)
- • Teams not on AWS (Azure Cosmos DB or MongoDB Atlas for multi-cloud)
- • Full-text search (DynamoDB has no text search — use OpenSearch or Algolia alongside)
Interface
Authentication
AWS SigV4 signing via IAM credentials or roles. IAM policies control table-level and attribute-level access. VPC endpoints keep traffic off public internet. Prefer IAM roles over access keys for agent workloads.
Pricing
Free tier is substantial for development. Production costs depend on read/write capacity mode — on-demand is simpler but more expensive at scale.
Agent Metadata
Known Gotchas
- ⚠ DynamoDB data model requires access patterns designed upfront — ad-hoc queries without proper indexes are expensive or impossible
- ⚠ Item size limit is 400KB — agents storing large documents must split or use S3 for large blobs with DynamoDB pointers
- ⚠ Scan operation reads entire table — never use Scan in production agent code; design with Query and indexes
- ⚠ DynamoDB Streams records expire after 24 hours — agents consuming streams must process within 24 hours or events are lost
- ⚠ Hot partition anti-pattern: sequential keys (timestamps, IDs) cause write throttling; use random prefixes or UUIDs for distributed writes
