+##### Command AckResponse
+
+An `AckResponse` is the broker’s response to acknowledge a request sent by the
client. It contains the `consumer_id` sent in the request.
+If a transaction is used, it contains both Transaction ID and Request ID that
are sent in the request.
+The client finishes the specific request according to the Request ID.
+If the `error` field is set, it indicates that the request has failed.
