Dear All,
I am working on IoT project. I am using paho library for Mqtt with mosquitto broker. I want to know if there is any limitation on number of Subscribers which can be created on a given instance of MqttClient.

I created a connection to the broker and want to subscriber to many topics. So it there any max limit on the number of subscription topics. Also want to know if there is any performance issues if no of subscribers are increased.

Please help.


Regards,
Rahul

Hi Rahul,

The MQTT protocol has no limits on the number of subscriptions. However you will be restrained by available memory.
