Kotlin Coroutines - Advanced Async Patterns

Expert guidance for complex async operations in Amethyst: relay pools, event streams, structured concurrency, and testing.

Mental Model

Async Architecture in Amethyst:

Relay Pool (supervisorScope)
    ├── Relay 1 (launch) → callbackFlow → Events
    ├── Relay 2 (launch) → callbackFlow → Events
    └── Relay 3 (launch) → callbackFlow → Events
            ↓
    merge() → distinctBy(id) → shareIn
            ↓
    Multiple Collectors (ViewModels, Services)
