HiveMQ

How many topic can the HiveMQ CE create?

If I create a topic for every client, so, when I have 1 million client, the HiveMQ CE must can support 1 million topic.
I want to know,Whether the HiveMQ CE has a limit on the number of topics?

Thanks!

Hi @long,

Nice to see your interest in the HiveMQ CE.
In MQTT topics are used dynamically, as they are communication channels used for routing of messages and cannot be thought of like topics in other typical message queuing mechanisms.
There is no fixed, technical limit on the number of topics you can use.

Hope this helps.

Florian
