Join Alexey Zimarev, the Event Sourcing enthusiast, Developer Advocate at Event Store and the author of "Hands-On Domain-Driven Design with .NET Core" book for a two days workshop for developers and architects who are willing to learn practical aspects of implementing Event Sourcing.
Today, many of us already heard about Event Sourcing and its benefits. However, when it comes to writing code, it could be quite challenging to start from an empty screen in the IDE. Using one of the Event Sourcing frameworks that promise to deliver everything out-of-the-box might be helpful at the beginning but also bring a great deal of "magic" to the system and hides a lot of important implementation details.
During the workshop, we will model and build an application using tactical patterns of DDD with CQRS and polyglot persistence. We will start with a quick modelling session to find out how the new system can be represented in a loop of commands, events and read-models. Then, during the course of the implementation exercise, we will create a set of useful abstractions and tools that you could continue to develop further and use them in your projects.
- Domain-Driven Design foundation blocks applied to Event Sourcing
- Modelling with domain events
- A whiteboard that compiles - convert sticky notes to code
- Commands, events and consistency boundaries
- Persistence for events
- Read-models and projections
- Production readiness - metrics and traces
- Evolving event-sourced systems
Alexey will write code in C# but participants can use any language. EventStore will be used to persist events. Prepare by setting up a client library for your language. The official client is available for .NET and community-driven libraries exist for Java, NodeJS, Python and other languages.
