单个消息中可以容纳多少数据MQTT？

[英]How much data can hold MQTT in single message?

原文 2017-01-19 10:00:01 0 1 mqtt

Is there any limit in sending(publishing) data to the topic (broker or receiver) in mqtt for single message? 在mqtt中向单个消息发送（发布）数据到主题（经纪人或接收者）是否有任何限制？

Thanks in advance.. 提前致谢..

IBM wrote an article about MQTT. IBM撰写了有关MQTT的文章。

A payload up to 256 MB could be attached in the packets. 数据包中最多可以附加256 MB的有效负载。 Having a small header overhead makes this protocol appropriate for IoT by lowering the amount of data transmitted over constrained networks. 头开销很小，可减少在受限网络上传输的数据量，从而使该协议适用于IoT。

There is a limit which is 256MB. 限制为256MB。
