New customer channels like click-and-collect require reliable data synchronization for things like price updates across many different applications and devices.
A simple push model for data updates is unreliable, so the transactional outbox pattern ensures events are persisted and processed reliably by a background worker.
To avoid sending large, unnecessary updates, deterministic hash values are calculated for data subsets to notify only the consumers affected by a change.
A picking app for fulfilling online orders must function reliably despite limited in-store internet, concurrency issues, and large, dynamic product catalogs.
Progressive Web Apps (PWAs) provide offline functionality through the Service Worker API, which acts as a network proxy to manage caching and data access.
The Cache API stores assets, IndexedDB holds persistent product data, and the Background Sync API defers updates until connectivity is restored.
The speakers answer audience questions about the specific technologies used, such as GreenRobot and Cosmos DB, and the rationale behind their architectural decisions.
