Somtimes large data files are needed in order to test database performance. One convenient way to generate large data files is by using BLOBs. The following code will generate a data file roughly the size of $n GBs.

var $b : Blob $n:=20 $gb:=1073741823 For ($i; 1; $n)    $e:=ds.Table.new()    SET BLOB SIZE($b; $gb; 0x00FF)    $e.blob:=$b    $e.save() End for

* Be careful not to set n so large that the machine running the test does runs out of disk space

Here is the definition of Table:
