Event Sourcing is like the Nessie, all heard about it but not much have seen it. The presentation will show how the moderns systems can benefit from that pattern with the practical examples using Marten (https://martendb.io/documentation/events/). Marten is an interesting framework that benefits from the great JSON support in Postgres. It makes it an Event Store (and DocumentDB) keeping benefits of the Event-Driven systems and allowing them to keep strong data consistency. All of that will be flavoured with a dose of CQRS and DDD.
