Hi Rodrigo -

It's not clear to me why you want this capability built into the DBMS 
engine.  Derby has managed to maintain a very small footprint by 
carefully weighing the benefit of adding new features and generally only 
implementing capabilities that are not available by utilizing existing 
technologies.   It seems that your request might be able to be handled 
by OS configuration.  If the goal of this is spreading I/O over multiple 
spindles (e.g. performance) then RAID arrays and disk-striping are good 
technologies to implement.  If none of these options meet your need then 
I recommend filing a feature request for DERBY in JIRA.  Be sure to 
explain the need and benefit of having the new feature.
