A startup needs a fully managed, MongoDB-compatible database that can store text embeddings and support similarity searches with a native vector index. Which AWS service should they choose?
Amazon DynamoDB
Amazon ElastiCache for Redis
Amazon Neptune
Amazon DocumentDB
Amazon DocumentDB offers native vector search indexes, letting teams persist embeddings and run similarity queries while using familiar MongoDB drivers and tools. Amazon Neptune is a graph database. Amazon DynamoDB is a key-value/NoSQL service that does not have native vector search capabilities but can integrate with other services like Amazon OpenSearch Service to provide it. Amazon ElastiCache for Redis provides in-memory caching rather than being primarily a managed document database.
