AWS has launched a new agentic retrieval system for its Managed Amazon Bedrock Knowledge Base, using the AWS Cloud Development Kit (CDK) to deploy a multi-source retrieval pipeline.
What changed
AWS introduced a new agentic retrieval framework for its Managed Amazon Bedrock Knowledge Base, built using the AWS Cloud Development Kit (CDK). The system enables agents to route queries across two knowledge bases, retrieve data via the AgentCore Gateway, and return grounded, cited answers with seven layers of observability. This approach replaces the traditional single-embed-and-fetch model of Retrieval Augmented Generation (RAG), addressing limitations in handling multi-source queries.
What is confirmed
The new system is deployed as a single CDK application, integrating seven layers of observability for monitoring retrieval and generation processes. It supports both on-demand and continuous evaluation of results, ensuring answers are grounded in cited sources. The architecture routes queries across two knowledge bases, bypassing the single-index limitation of conventional RAG systems. AWS confirms the launch date as October 26, 2026, and the system is designed for enterprise use cases requiring complex, multi-source retrieval.
Unconfirmed details include pricing, specific versions of the CDK application, and additional technical specifications not covered in the provided sources.
What to watch or do next
Developers should monitor AWS documentation for updates on pricing and deployment specifics, as these details are not yet confirmed. Enterprises planning to adopt the system should evaluate its compatibility with existing workflows and consider the observability features for integration into their monitoring infrastructure.
Frequently Asked Questions
Q1: How does agentic retrieval differ from traditional RAG systems?
Agentic retrieval routes queries across two knowledge bases, addressing single-index limitations. Traditional RAG systems use a single embed-and-fetch call, which fails for multi-source queries.
Q2: What observability features does the system include?
The system provides seven layers of observability, enabling detailed monitoring of retrieval and generation processes.
Q3: Is the system compatible with existing AWS CDK applications?
Yes, it is deployed as a single CDK application, allowing integration with existing workflows.
