Amazon Bedrock Knowledge Bases now supports Amazon OpenSearch Managed Cluster for vector storage

We are announcing the support of Amazon OpenSearch Managed cluster as a vector store in Amazon Bedrock Knowledge Bases. Amazon Bedrock Knowledge Bases securely connects foundation models (FMs) to internal company data sources for Retrieval Augmented Generation (RAG), to deliver more relevant and accurate responses. Amazon Bedrock Knowledge Bases’ native integration with vector databases allows you to mitigate the need to build custom data source integrations. With this launch, you can use OpenSearch managed cluster as the vector database to take advantage of the [suite of features](https://docs.aws.amazon.com/bedrock/latest/userguide/kb-test-config.html) available in Bedrock Knowledge Bases. This integration adds to the list of vector databases supported by Bedrock Knowledge Bases, including Amazon OpenSearch Serverless, Amazon Aurora, Amazon Neptune Analytics, Pinecone, MongoDB Atlas, and Redis. The OpenSearch Managed cluster integration for Amazon Bedrock Knowledge Bases is now generally available in all existing Amazon Bedrock Knowledge Base and OpenSearch service regions. To learn more, refer to the [Knowledge Bases documentation.](https://docs.aws.amazon.com/bedrock/latest/userguide/knowledge-base-prereq.html)
