Reactive Microservices Event Sourcing Architecture with Type Safety

microservices event-sourcing CQRS type-safety distributed-systems
Prompt
Design a comprehensive event sourcing microservices architecture for a distributed SaaS platform using TypeScript with Nest.js. Create a strongly-typed event stream system that guarantees type safety across different service boundaries, implementing CQRS patterns with generic event reducers. Include robust error handling mechanisms, implement versioned event schemas, and demonstrate how to handle event migration and backward compatibility using TypeScript's advanced type system and discriminated unions.
