Explanation
Amazon OpenSearch Service is the correct choice for this scenario because:
-
Vector Database Capabilities: OpenSearch supports vector similarity search, which is essential for storing and querying embeddings efficiently
-
Full Control: As a self-managed service, OpenSearch allows complete control over database configuration, clustering, and performance tuning
-
Scalability: Can handle millions of embeddings with distributed architecture
-
Integration with Amazon Bedrock: Works well with AI/ML services for embedding-based applications
-
Financial Services Compliance: Supports security features needed for financial data
Other options are less suitable:
-
Amazon RDS: Traditional relational database, not optimized for vector operations
-
Amazon DynamoDB: NoSQL database, lacks native vector search capabilities
-
Amazon Aurora: Relational database, not designed for vector embeddings
-
Amazon Neptune: Graph database, not optimized for vector similarity search
-
Amazon MemoryDB for Redis: In-memory database, can support vectors but OpenSearch is more purpose-built for this use case
OpenSearch provides the best combination of vector search capabilities, scalability, and configuration control for embedding storage and retrieval.
