Set security user processor [ingest-node-set-security-user-processor]

Sets user-related details (such as username, roles, email, full_name, metadata, api_key, realm and authentication_type) from the current authenticated user to the current document by pre-processing the ingest. The api_key property exists only if the user authenticates with an API key. It is an object containing the id, name and metadata (if it exists and is non-empty) fields of the API key. The realm property is also an object with two fields, name and type. When using API key authentication, the realm property refers to the realm from which the API key is created. The authentication_type property is a string that can take value from REALM, API_KEY, TOKEN and ANONYMOUS.

The following example adds all user details for the current authenticated user to the user field for all documents that are processed by this pipeline:

{

      "set_security_user": {
        "field": "user"
      }
    }
