sasauz / deny-wildcard-plugin

A plugin for the HiveMQ MQTT broker which denies all subscriptions to "#" and disconnects the client

Deny Wildcard Subscription Plugin

Note	HiveMQ 4 uses a new extension system. This HiveMQ 3 plugin is not compatible with HiveMQ 4. The new version can be found here.

This plugin denies any subscription to the root wildcard topic. In general, root wildcard subscribers tend to be a bottleneck in many scenarios.

Any client who wants to subscribe to the root level wildcard will be disconnected immediately.
