The change feed in Azure Cosmos DB is one of the most overlooked features of Microsoft’s globally distributed, massively scalable, multi-model database service. Similar to the transaction log of a relational database, the change feed gives you a continuous record of changes as they occur. It therefore serves as an excellent event source for a wide range of cloud-based microservices targeting ecommerce, IoT, and other large-scale scenarios. In this demo-filled session aimed at developers and data professionals alike, you’ll learn how to leverage the change feed and build event-driven microservices with Azure Functions to achieve replication, denormalization, notifications, materialized views, and data archival.

You will learn:

  • About the change feed in Azure Cosmos DB
  • Explore event-driven microservices enabled by leveraging the change feed
  • Watch live demos using the Change Feed Processor library with Azure Functions
