[Docs] Topics sent a MQTT retained message are not automatically deleted even if messageCount=0

XMLWordPrintable

      • Topics("$sys.mqtt.retain.xxx") sent a MQTT retained message are not automatically deleted even if messageCount=0, such as when the message expires or a zero-length payload is sent.
      • As of now, this behavior is considered expected, however, when using a large number of MQTT topics, unnecessary topics may remain and consume unnecessary resources.
      • And the workaround requires manually deleting unused topics, so this is inconvenient for users.
