Memory usage

[Karl-Heinz Zengerle <ka...@sawag.com>]

Hi world.
 
I'm developing a report pushing possibly much data from a database into
an Excel file.
 
Because of this I read just portions from the database into memory and
push them to the proper POI objects. So at his side I need just a
limited amount of memory.
 
Does POI keep all information in memory? Or does it load just parts
which are explicitly queried, modified or inserted?
 
MfG

The whole lot.  Memory usage is one area of POI we are trying to 
improve.  Regardless of this it's always going to be the whole file because 
of the way Excel files are structured.
