Azure Cosmos DB has versatile hidden feature: the change feed. The Change Feed allows apps to subscribe to Cosmos DB for inserts and updates on data. When this happens, the changes are published to the change feed as an event, and code can respond to the changes rather than polling the database or having to create complex dataflows. In this video, we'll set one up and show you how easy it is to use.
