Developers should learn Realm when building mobile apps that require high-performance local data storage with real-time updates, such as chat applications, collaborative tools, or offline-capable apps meets developers should use room when building android apps that require local data storage, as it offers a more efficient and less error-prone alternative to raw sqlite. Here's our take.

Realm

Room Persistence Library

Developers should use Room when building Android apps that require local data storage, as it offers a more efficient and less error-prone alternative to raw SQLite

Pros

• Related to: android-jetpack, sqlite

Cons

• Specific tradeoffs depend on your use case
