Clusters

Aedes needs on disk dbs like MongoDB and Redis in order to work with clusters. Based on our tests and users reports the best performances/stability are reached when using aedes-persistence-mongodb paired with mqemitter-redis.

Other info:

Bridge connections

Normally, when publishing a message, the retain flag is consumed by Aedes and then set to false. This is done for two reasons:

Brokers that support the Bridge Protocol can connect to Aedes. When connecting with this special protocol, subscriptions work as usual except that the retain flag in the packet is propagated as-is.

Acknowledgements

This library is born after a lot of discussion with all Mosca users and how that was deployed in production. This addresses your concerns about performance and stability.

Mosca vs Aedes

Example benchmark test with 1000 clients sending 5000 QoS 1 messsages. Used mqtt-benchmark with command:

mqtt-benchmark --broker tcp://localhost:1883 --clients 1000 --qos 1 --count 5000

Security notice

Messages sent to the broker are considered valid once they pass the authorizePublish callback. In other terms, if permissions for the given client are revoked after the call completes, the message is still considered valid. In case you are sending time-sensitive messages, make sure to use QoS 0 or connect with a clean session.

Support

If there are bugs/leaks in production scenarios, we encourage people to send Pull Request and/or reach out maintainers for some paid support.
