AWS CDK Reference

Appearance

v2.275.0

Experimental

@aws-cdk/aws-bedrock-alpha is an experimental (alpha) package: its API may change in any release, without a major version bump.

KnowledgeBaseSupplementalDataStorage Mixin ​

Stores the images, audio and video a vector knowledge base extracts from multimodal documents in an Amazon S3 bucket.

Merges SupplementalDataStorageConfiguration into the existing vector configuration, replacing any location already set. Grants the role referenced by the knowledge base's roleArn s3:ListBucket on the bucket and s3:GetObject, s3:PutObject and s3:DeleteObject on its objects, and makes the knowledge base depend on that policy.
