A practical example; multiple subscribers; the query model and storing calculated data. Why not use a database. Correcting an error in a historical event. Using the stream on a new application. Scenarios where event sourcing applies. Technologies to use, Event Store, Marten, Apache Kafka, CosmosDb. Using Azure. Versioning data, and changing shapes of data. Libraries to make this easier. Future of event sourcing. How to get started. How to find David.
