How lightCellsDataProvider is working in 7.0.4

Hi team,

we are upgraded from 2.5.17 to 7.0.4.

we are using LightCellsDataProvider for excel generation .

in initially pop is came after clicking save/open then file generation was started.

but i did not noticed any such thing with latest jar files. it will wait for complete file generation after it will download the file.

this not useful in our case. we are not interested to show the blank screen to user until the file generation is completed.

and we are getting out of memory error for 59 columns and 10,00,000 rows.

please find the attached code.

and help on this will be appreciated.
