MongoDB Mobile Features¶
On this page
Deprecation
MongoDB has deprecated MongoDB Mobile. We are focusing our efforts on Realm, the most popular database for mobile devices.
Overview¶
MongoDB Mobile is an smaller version of the MongoDB database, optimized to run on mobile and IoT devices. The following sections define the platforms supported, and the feature differences between MongoDB Mobile and MongoDB.
Platform Support¶
MongoDB Mobile supports development on the following devices:
| OS | OS Version | Target Architecture |
|---|---|---|
| iOS | 11+ | armv8-a |
| iOS Simulator | 11+ | x86_64 |
| tvOS | 10.2+ | armv8-a |
| tvOS Simulator | 10.2+ | x86_64 |
| watchOS | 4.3+ | armv7-k |
| watchOS Simulator | 4.3+ | i386 |
| Android | 5.0+ (Lollipop) | armeabi-v7a |
| Android | 5.0+ (Lollipop) | arm64-v8a |
| Android | 5.0+ (Lollipop) | x86_64 |
Comparing MongoDB and MongoDB Mobile¶
To improve the size and performance of MongoDB Mobile, some components found in MongoDB 4.0 are not included in the mobile version. The following list details the components that are not included:
- Sharding and Replication
MongoDB Mobile operates as a standalone instance with a single node present on the mobile device.
- Storage Engine Configuration
MongoDB Mobile uses SQLite as a simple key-value store behind the scenes due to its stability and prevalence on devices. As such, MongoDB Mobile does not provide the ability to configure the underlying SQLite deployment or use other storage engines.
- Database Authentication
MongoDB Mobile only accepts connections that originate from within the application. These connections are trusted, so database authentication is disabled in MongoDB Mobile. When moving data between MongoDB Mobile and an external component, we recommend using a combination of authentication and security rules on the server-side.
- Encryption/SSL
MongoDB Mobile does not use SSL for connections to the local database. However, when using the Stitch SDK to transfer data outside of the device, connections are encrypted with SSL.
Additionally, MongoDB Mobile does not provide encryption at rest. MongoDB recommends that users encrypt necessary fields within the application before storing the data in MongoDB Mobile.
- Change streams
MongoDB Mobile databases do not support the creation of change streams.
- Server-side JavaScript Execution
MongoDB Mobile does not support Server-side JavaScript execution.
- Transactions
MongoDB Mobile does not support transactions.
