CreateKnowledgeBase
Creates a knowledge base. A knowledge base contains your data sources so that Large Language Models (LLMs) can use your data. To create a knowledge base, you must first set up your data sources and configure a supported vector store. For more information, see Set up a knowledge base.
Note
If you prefer to let Amazon Bedrock create and manage a vector store for you in Amazon OpenSearch Service, use the console. For more information, see Create a knowledge base.
-
Provide the
nameand an optionaldescription. -
Provide the Amazon Resource Name (ARN) with permissions to create a knowledge base in the
roleArnfield. -
Provide the embedding model to use in the
embeddingModelArnfield in theknowledgeBaseConfigurationobject. -
Provide the configuration for your vector store in the
storageConfigurationobject.-
For an Amazon OpenSearch Service database, use the
opensearchServerlessConfigurationobject. For more information, see Create a vector store in Amazon OpenSearch Service. -
For an Amazon Aurora database, use the
RdsConfigurationobject. For more information, see Create a vector store in Amazon Aurora. -
For a Pinecone database, use the
pineconeConfigurationobject. For more information, see Create a vector store in Pinecone. -
For a Redis Enterprise Cloud database, use the
redisEnterpriseCloudConfigurationobject. For more information, see Create a vector store in Redis Enterprise Cloud.
