Operating Limitations

Background

If there are no limitations on connection numbers or data transmission, users may experience reduced MQTT broker performance, such as a slow network connection or operation response, prolonged message latency, message accumulation, or even message discards, and other issues. On the other hand, the protocol limitation also specify the usage limits.

EMQX has therefore specified the following quotas and usage limits for some of the major features.

Reference List

The operating limitations can be classified into:

• Broker resource limitation: Theoretically, there is no maximum limit. The actual limit varies with the server specification.
• Hard coding or protocol limitation: EMQX has set these limitations to comply with the protocols or to ensure stable performance. In some projects, EMQX has modified the default setting (as specified in the protocol) to a more reasonable value. You can change the setting with our configuration file.
