Understanding Realm Sync
How Realm Sync Works
Realm Sync is a synchronization mechanism that allows data changes in a local Realm database to be automatically reflected in a MongoDB Atlas cluster, and vice versa. Here’s a high-level overview of how it works:
- Initial Sync: When a client connects to the server, an initial sync is performed, ensuring that the local database contains the most recent data from the server.
- Live Sync: As changes are made on either the client or the server, they are propagated in real-time. This bidirectional synchronization ensures that all instances of the database remain consistent.
- Conflict Resolution: Realm Sync handles conflicts through a deterministic merging process, ensuring that changes are integrated seamlessly.
Benefits of Realm Sync
- Real-Time Updates: Ensures that all connected clients have the latest data instantly.
- Offline Support: Allows applications to function offline and sync changes when reconnected.
- Ease of Use: Simplifies synchronization logic, reducing development complexity.
- Security: Data is transmitted securely with encryption in transit and at rest.
Realm Sync And Local Cohabitation In MongoDB
MongoDB Realm is a mobile database solution that simplifies data synchronization and provides real-time capabilities for mobile and web applications. Realm Sync ensures that data is seamlessly synchronized between the client and server, allowing for offline-first experiences. However, developers often need to balance the use of Realm Sync with local data storage and access patterns. This article explores how to manage Realm Sync and local data cohabitation in MongoDB to build efficient and robust applications.
