AWS Amplify DataStore
AWS Amplify DataStore provides an on-device repository for applications that read, write, and observe data online or offline.
What AWS Amplify DataStore is
AWS Amplify DataStore provides an on-device repository for applications that read, write, and observe data online or offline. Data can remain local, or synchronize bidirectionally with the cloud and across devices. GraphQL data models become models for JavaScript, Swift, Java, or Dart applications, with mobile support for iOS, Android, React Native, and Flutter. Through its API, applications can save, query, update, delete, and observe records. SQLite and IndexedDB storage adapters are available. Synchronization includes Delta Sync and conflict strategies such as Auto Merge, Optimistic Concurrency, and custom Lambda handling. When cloud sync is enabled, Amplify CLI can deploy AppSync and DynamoDB resources. Authorization rules can apply at model or field level, and clients can subscribe to real-time updates. The former DataStore page redirects to Amplify Data, while AWS documentation says DataStore will receive no new features and provides migration guidance. Pricing starts at $0.01, with no free plan.
