In short,
It is about asynchronous notification system. Available both - locally and in vClient-vServer environments.
There are "channels" to send/receive messages. You can send message ( any string ) to the channel and you can subscribe to receive messages from the channel. Both - API and SQL way are available. To receive notifications from some channel you should subscribe it first and wait for the messages - it could be another thread or just checking for the messages periodically from the main thread.

How to use it - depends on your needs. It could be:
- simple chat system, say, to receive notifications from admins;
- async app-specific channels for specific events;
...
