Delete an Amazon Bedrock knowledge base - Amazon Bedrock

Delete an Amazon Bedrock knowledge base

You can delete or remove a knowledge base that you no longer use or need. When you delete a knowledge base, you should also carry out the following actions to fully delete all resources associated with the knowledge base.

  • Dissociate the knowledge base from any agents it's associated with.

  • Delete the vector store itself for your knowledge base.

Note

The default dataDeletionPolicy on a newly created data source is "Delete", unless otherwise specified during data source creation. The policy applies when you delete a knowledge base or data source resource. You can update the policy to "Retain" data from your data source that's converted into vector embeddings. Note that the vector store itself is not deleted if you delete a knowledge base or data source resource.

Select the tab corresponding to your method of choice and follow the steps:

Console
To delete a knowledge base

  1. Before the following steps, make sure to delete the knowledge base from any agents that it's associated with. To do this, carry out the following steps:

    1. From the left navigation pane, select Agents.

    2. Choose the Name of the agent that you want to delete the knowledge base from.

    3. A red banner appears to warn you to delete the reference to the knowledge base, which no longer exists, from the agent.

    4. Select the radio button next to the knowledge base that you want to remove. Select More and then choose Delete.

  2. Sign in to the AWS Management Console using an IAM role with Amazon Bedrock permissions, and open the Amazon Bedrock console at https://console.aws.amazon.com/bedrock/.

  3. From the left navigation pane, select Knowledge bases.

  4. Choose a knowledge base or select the radio button next to a knowledge base. Then choose Delete.

  5. Review the warnings for deleting a knowledge base. If you accept these conditions, enter delete in the input box and select Delete to confirm.

    Note

    The vector store itself is not deleted, only the data. You can use the vector store's console or SDK to delete the vector store. Make sure to also check any Amazon Bedrock agents that you use with your knowledge base.

API

To delete the knowledge base, send a DeleteKnowledgeBase request with a Agents for Amazon Bedrock build-time endpoint.

You must also disassociate the knowledge base from any agents that it's associated with by making a DisassociateAgentKnowledgeBase request with a Agents for Amazon Bedrock build-time endpoint.

You must also delete the vector store itself by using the vector store's console or SDK to delete the vector store.
