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 is a persistent record of changes to a container in the order they occurred. 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 session, Callon will introduce Azure Cosmos DB Change Feed and how to leverage it as an event source and access using Azure Functions.
