How much data can hold MQTT in single message?

Question

Is there any limit in sending(publishing) data to the topic (broker or receiver) in mqtt for single message?

Thanks in advance..

Answer 1

IBM wrote an article about MQTT.

A payload up to 256 MB could be attached in the packets. Having a small header overhead makes this protocol appropriate for IoT by lowering the amount of data transmitted over constrained networks.

There is a limit which is 256MB.
