> e.g., analytics are being continuously performed and new results generated
> say every 1min but under "normal" conditions a "normal" result is only
> published (equivalently an IotDevice event generated) every 30min. Some
> alert condition is detected by local analytics and the application wants to
> start publishing the results every 1min.
