Azure Messaging services: detecting the absence of a message

Question

Within an Azure micro-services environment, implementing an event driven architecture, I have the challenge of acting upon a received event. I also have the counter challenge of detecting a duration with no events.

Has anyone identified a way in which the recipient can be notified after a period of no events?

I have considered things like Azure functions polling the dataset however this won't scale particularly well due to the volume of data.

You could use Azure Stream Analytics, and Windowing to detect if a window, eg the last x minutes, did not contain any new events. See here for a similar answer: https://stackoverflow.com/a/53430421/1537195
