Large Datasets

I am looking for some guidence.

I have a large data set 500,000 rows of GPS data which with a unique lat/lng.

I am using openLayers to find if a gps location is inside a boundary. Which all works with smaller datasets.

Is it possible to load data in short batches 1000 rows. Do the calculation using the onRowCreated event. Then reload the next batch using the same grid. I do not want to extend the grid.

Would I use the onXLS event to load the next batch ?

How would I check when all the dataset is loaded is there an example.

Any help would be great thanks.


You may try to use the dynamic loading in your grid. Here you can find a tutorial: … ep_by_step
