    - `resource_name` string, uri — Resource Name is a Uniform Resource Identifier (URI) that is globally unique across space and time. It is represented as a Confluent Resource Name
    - `created_at` string, date-time — The date and time at which this object was created. It is represented in RFC3339 format and is in UTC.
    - `updated_at` string, date-time — The date and time at which this object was last updated. It is represented in RFC3339 format and is in UTC.
    - `deleted_at` string, date-time — The date and time at which this object was (or will be) deleted. It is represented in RFC3339 format and is in UTC.
