通过 AWS IoT Basic 摄取发送的消息是否无法到达订阅者（与 MQTT 或 HTTP 不同）？
Do messages sent via AWS IoT Basic ingest not reach subscribers (unlike MQTT or HTTP)?
设备可以通过 MQTT、HTTP 或基本摄取向 AWS IoT 规则引擎发送消息。规则引擎使用SQL查询来监听主题，并在匹配FROM子句的主题到达时选择数据。
发送MQTT消息的代码：
device.publish('topic/subtopic, payload)
通过基本摄取发送消息的代码是：
device.publish('aws/rules/topic/subtopic, payload)
URL 通过 HTTP POST 发送消息是：
https://IoT_data_endpoint/topics/url_encoded_topic_name?qos=1
MQTT 涉及代理 (pub/sub)。因此，通过 MQTT 发送到主题的消息将到达所有订阅者。同样，通过 HTTP 发送的消息也将到达所有订阅者。由于基本摄取绕过了代理，因此节省了成本，而且由于不涉及代理，因此消息不会到达任何订阅者。我理解正确吗？
Where as basic ingest bypasses the broker, thus saving cost and also since broker is not involved the message will not reach any subscribers. Have I understood this correctly?
正确 - MQTT 订阅者将不会收到使用基本摄取发送的消息，因为代理被绕过。

Basic Ingest enables you to send data to only cloud services through the Rules Engine.
MQTT 客户端无法订阅基本摄取保留主题：
Your devices and rules cannot subscribe to Basic Ingest reserved topics
