The development of Async Collections in SignalDB is aimed at enhancing the database's flexibility and performance, particularly in scenarios where data persistence without in-memory storage is essential. These Async Collections would enable SignalDB to interact with asynchronous storage mechanisms like IndexedDB more efficiently, allowing for data operations without necessarily storing data in the client's memory. This feature is especially relevant for applications that handle large datasets or require extended data persistence beyond the session scope. Furthermore, Async Collections could facilitate the outsourcing of query execution to Web Workers, thereby offloading intensive data processing tasks from the main thread. This approach would significantly improve the application's responsiveness and overall performance, especially in web applications with complex data processing requirements. The introduction of Async Collections in SignalDB aims to provide developers with more options for data management, catering to a broader range of application architectures and performance needs.
