Mike Matrigali commented on DERBY-6809:
---------------------------------------
See derby.storage.sortBufferMax property use in derby tests and the sort code
for a tuning knob that is useful for writing developer tests to control in
memory vs external sort. This knob is not meant for public use as it is hard
to document in terms an application would prefer. It controls number of sort
items rather than amount of memory. Not sure if java still gives app code a
good way to know how
much memory is being used for N rows containing user data of varying types and
lengths.
