First, use ActiveDataProvider to configure query, paging size and sorting in the controller, and then use GridView to automatically render paging controls in the view; for performance optimization, when the data volume is huge, COUNT(*) overhead should be avoided, and totalCount can be set to false or use estimates; further improve performance, cursor-based keyset pagination can be used to use index columns (such as ids) for range query to avoid performance degradation caused by OFFSET, and is suitable for infinite scrolling fields.
