You might have heard about change feed as it's been making its way to more and more data and storage services. But very likely you haven't yet had a chance to play with any of its implementations and understand it more thoroughly. I want to help you with that.

Change feed sparked my interest back in 2018 when I was involved in a project that was using quite an exotic database (RethinkDB). Since then I participated in several projects where I had an opportunity to use change feed provided by various services. The one I ended up using the most is the implementation provided by Azure Cosmos DB. In this talk, I want to share my knowledge about it.

Join me and learn what are the main characteristics of any change feed and what is unique about the Azure Cosmos DB one. You will see how you can integrate it with other services by implementing different consumption patterns or using existing no-code integrations. We will also explore the most fitting usage scenarios and a potential alternative.
