I agree, as well.  And in fact, the need for such a suite came up when I was 
working with DERBY-121.  The test case that I wrote for DERBY-121 requires a 
rather large LOB to be passed to Network Server, which means the server JVM 
needs more heap than usual.  While this probably isn't a "large data volume" 
like what you were envisioning, it nonetheless is a similar sort of 
thing--namely, it's a test that requires extra machine resources and thus 
shouldn't be run as part of "derbyall".

As part of my patch for DERBY-121, I created a new suite "largeData" that is 
fairly generic and that can (hopefully) be expanded/extended to help satisfy the 
requirements described by Mike in this thread.  See the following email for that 
patch and a description of what I did with the new suite:


And please make comments if you think the new suite could be organized better to 
fit the needs described in this thread (at least, the "large data volumne" 
needs).  Remember: the new suite is only meant to be a starting place; it's not 
(yet) intended to satsify all of the large data/long-running test requirements...
