Domain Modeling for Event-Sourced Data 

• Date: August 20 | Time: 16:10–16:50
• Location: Creative and Mix 

Unlock system flexibility by separating read and write models in event-sourced architectures. In this talk, you’ll learn how to model the read side using Scala’s powerful type system and functional features—creating resilient, expressive models over non-SQL event stores. 

• Separating read/write concerns for maintainability 
• Schema evolution in long-lived systems 
• Performance patterns and access strategies 
• Building safe, composable DSLs with Scala 

See how real-world systems apply this approach to reduce coupling, improve correctness, and evolve with agility.
