가상 스크롤링으로 대규모 데이터 그리드를 최적화하세요

Virtual scroll support in a grid component is a rendering strategy that displays only the rows and columns currently visible in the viewport while dynamically loading and unloading data as the user scrolls. It minimizes DOM size and memory usage by avoiding the creation of off-screen elements, which improves rendering speed, reduces layout thrashing, and maintains smooth interaction even with very large datasets. This approach enables grids to handle millions of records efficiently without requiring pagination, lowers CPU and GPU load, and delivers consistent performance across a wide range of devices.

Several React grid controls offer virtual scroll capability including:

• DevExtreme React Data Grid (part of DevExtreme Complete by DevExpress) lets you render only visible records offering excellent performance for displaying thousands of data rows.
• KendoReact Data Grid (part of KendoReact by Telerik) allows you to virtualize grid content for rapid scrolling and reduced DOM overhead with large datasets.
• Wijmo React DataGrid (FlexGrid) (part of Wijmo by MESCIUS) facilitates virtual scrolling that loads data on demand, minimizing rendering work and preserving fluid navigation.
• Infragistics Ignite UI for React Data Grid (part of Infragistics Ignite UI) enables row and column virtualization to significantly boost performance for large datasets.
