Why this service matters
AppSync is a managed GraphQL + Event API service. It provides a unified data layer over multiple backends with real-time and offline capabilities.
Power:
- Real-time subscriptions (WebSocket-based)
- Offline support with conflict resolution
- Multiple data sources (DynamoDB, Lambda, HTTP, RDS, OpenSearch, EventBridge)
- Built-in caching (server-side, per-resolver)
- Merged APIs (compose multiple source APIs into one endpoint)
Important workflows
- Design - Configure service behavior for your workload.
