Breakout Beijing-2016 Subscriptions

Clarification of Event types

Distinction/Requirements:

• Self-containing vs. Delta (does a single sample make sense?)
• Severity of loss / ensured delivery (can samples be lost?)
• Equidistance in time vs. spontanous occurence (are samples equidistant?)
• History/Buffer vs. only most recent value (can I get a specific set of samples from the past?)

Micro use cases / application patterns

1. Microfone

2. Alarms, doorbell
   • self-contained
   • ensured delivery
   • spontanous
   • no keeping of history
3. Delta-Temperature sensor, dimmer control and lights
   • no equidistance
   • no ensured delivery needed
   • selfcontained
   • most recent value
4. Sampled Temperature sensor
