When dealing with very large datasets in grids, loading all data at once can lead to significant performance issues and a poor user experience due to long initial rendering times.
Describe the solution you'd like
Implement an optimized rendering mechanism for grids that supports chunked data loading from stores. This involves:
src/data/Store.mjs: Enhance the load event to include a postChunkLoad flag, indicating when a load operation is part of a larger chunked data transfer.src/grid/Body.mjs:
- Introduce internal flags (
#initialChunkSize, #initialTotalSize) to manage the state of chunked loading.
- Modify the
createViewData method to initially render only the first data chunk received, rather than attempting to render the entire (potentially very large) dataset at once.
- Adjust
getRowId and updateScrollHeight to correctly account for the initial chunked rendering.
- Conditionally execute post-load operations (like scrolling) only after the full data set is loaded, not after each chunk.
This optimization will allow grids to display data much faster when dealing with large datasets that are loaded incrementally, providing a smoother and more responsive user experience.
Describe alternatives you've considered
(No specific alternatives considered as this is an optimization of an existing process for chunked data.)
Additional context
This feature is based on the changes introduced in commit e76ed9180e32027c157a5615305a824ef820de91.
