Ditto 4.10 SDK introduces significant advancements, enhancing developer flexibility, performance, and platform support. The update includes improved data synchronization controls, expanded Ditto Query Language (DQL) capabilities, and essential bug fixes, making it a more powerful tool for application development. Notably, it now supports React Native Expo and offers fine-grained control over data synchronization, enabling configurations for local-only, cloud-only, or nearby peer syncs. Multi-threaded store observers enhance performance under high loads, while new DQL features include pattern matching and batch operation controls. An experimental hot restarting feature for Flutter is also previewed, aimed at improving the development workflow. Additionally, critical bug fixes and performance optimizations, such as smoother Linux BLE initialization and enhanced Android stability, contribute to the SDK's reliability.
