The request mentions SubscriptionPushConsumer and IoTDB versions 1.3.3 or 2.0.3, but names no files or tests. Start by locating the subscription consumer implementation and its existing usage or tests; done would require a defined push-mode behavior and corresponding implementation or documentation.
