public boolean isCompressTempFiles()
public void setCompressTempFiles(boolean compress)
SXSSF writes sheet data in temporary files (a temp file per-sheet)
and the size of these temp files can grow to to a very large size,
e.g. for a 20 MB csv data the size of the temp xml file become few GB large.
If the "compress" flag is set to true
then the temporary XML is gzipped.
Please note the "compress" option may cause performance penalty.
Setting this option only affects compression for subsequent createSheet()
calls.
