Amazon S3 Vectors and Amazon OpenSearch Service have been integrated for vector search optimization. The two services offer flexible vector storage, cost-effective solutions, and advanced features like hybrid search, advanced filtering, and geo-filtering. Users can now store vectors in S3 Vectors and query them in OpenSearch Service, or export vectors from S3 Vector Index to OpenSearch Serverless Collection for high-performance vector search. This integration enables users to optimize for cost, latency, and accuracy by intelligently distributing vector workloads between S3 Vectors and OpenSearch Service.
