Event Sourcing is nothing more than storing current state as a series of events and rebuilding system state by replaying that series of events. Cosmos DB, the multi-model globally distributed database service on Azure is a great fit for implementing event sourced systems. • In this episode, Sander Molenkamp will show you how to build an event store on Cosmos DB. Topics include bulk operations using stored procedures, adding a domain layer, and projections using the Cosmos DB Change Feed. All while being globally-distributed, and without deploying or managing any servers. • 00:00:10 - Introduction • 00:01:20 - Case: Energy Insights project • 00:05:00 - Storing current state vs Event Sourcing • 00:08:15 - Let’s build an Event Store! • 00:11:35 - Demo: Working with streams • 00:21:28 - Demo: Adding a domain layer • 00:32:03 - Querying event streams • 00:37:10 - Demo: Projections • 00:45:50 - Wrap up • Demo code: • https://github.com/amolenk/CosmosEven... • This video was made possible by Info Support (https://www.infosupport.com) and DotNed, the Dutch .NET Usergroup (https://www.dotned.nl). • --
