Easy, Database Agnostic .NET Event Sourcing and CQRS with Akka.NET

Event sourcing is a powerful, self-auditing technique for tracking changes to entities in a given business system - and frequently event-sourcing goes hand-in-hand with Command Query Responsibility Segregation (CQRS), a powerful pattern for separating read and write models from each other.

Akka.NET is one of the best solutions in market for implementing both of these patterns using Akka.Persistence (event-sourcing) and Akka.Persistence.Query (CQRS) - it can work across any of our supported databases (SQL Server, Postgres, Redis, MongoDb, Azure Table Storage, to name a few) and it does so with minimal fuss.

In this webinar you’ll learn:

- How to leverage Akka.Persistence for event-sourcing your source-of-truth data;
- How to design state and event formats your persistent actors will use;
- How to project Akka.Persistence data using Akka.Persistence.Query into separate read models - such as materialized views, read-optimized tables, and more;
- How to use tags and other Akka.Persistence features to make your read models as flexible as possible; and
- How to version your events and state across the lifespan of your software.
