Publish data from MQTT topics to Google cloud pubsub topics

Question

I am using paho.mqtt.client to read data from mqtt topic. Is there any way to publish data from multiple Mqtt topics to multiple Google Pubsub topics, ie mqtt_topic in Mqtt -> gcp_topic in Google cloud pubsub?

Answer 1

If you are using python then in order to send multiple messages to multiple topics using paho.mqtt you can use publish.multiple in python eg

msgs = [{'topic':"paho/test/multiple", 'payload':"multiple 1"},
        ("paho/test/multiple", "multiple 2", 0, False)]
publish.multiple(msgs, hostname="mqtt.eclipse.org") 

for further information take a look at the official documentation:
