AWS::Bedrock::Flow KnowledgeBaseFlowNodeConfiguration
Contains configurations for a knowledge base node in a flow. This node takes a query as the input and returns, as the output, the retrieved responses directly (as an array) or a response generated based on the retrieved responses. For more information, see Node types in a flow in the Amazon Bedrock User Guide.
Syntax
To declare this entity in your AWS CloudFormation template, use the following syntax:
