Best Practices for Working with Realm

Proper Data Structuring

The data should be structured according to the project's needs. It is necessary to use suitable data types and create indexes to accelerate queries, as well as to ensure proper data segmentation between objects, avoiding information duplication.

Working with Threads

Realm should be used in the thread it was created in. When necessary to work with Realm in different threads, it is required to create a new Realm instance in each thread and close Realm instances when they are no longer needed.

Performance Optimization

It is recommended to use lazy data loading where possible, and avoid excessive data normalization, as it can reduce performance. Also, avoid excessive use of transactions as they can lower performance.

Adding Error Handling

It is necessary to support error handling at all stages of interaction with Realm. This will help avoid unexpected situations and simplify application debugging.


It is necessary to test working with Realm under various conditions: with a large amount of data, in multithreading, when working offline. This will help identify and eliminate potential problems before the application is launched in production.

Realm is a powerful and flexible tool for working with data on mobile devices. Its performance, scalability, and support for multiple platforms make it a great choice for application developers.
