What is Change Data Capture for mobile sync?

CDC streams database changes from WAL logs to apps via tools like Debezium, replacing polling for real-time, low-load sync.

Does CDC work with Kotlin Multiplatform?

Yes — pair Debezium SSE pushes with KMP clients for cross-platform (Android/iOS) cache invalidation.

Absolutely, with outbox pattern. Lower complexity, better scaling for unidirectional mobile updates.
