  title: Amazon Kendra Teardown Data Source and Index
  summary: Delete a data source connector, confirm it is gone, then delete the index that owned it.
  description: >-
    Cleanly decommissions an Amazon Kendra index by first deleting its data
    source connector, polling ListDataSources until the deleted connector no
    longer appears, and then deleting the index itself. Tearing the connector
    down before the index avoids orphaned crawl state. Each step inlines its
    request, including the AWS JSON protocol X-Amz-Target header, so the flow can
    be read and executed without opening the underlying OpenAPI description.
