Yes, but there are other options. For example, a Lookup stage can perform a "sparse" lookup directly to a DB2 or Oracle table. Almost no impact on memory whatsoever. Ask yourself whether a lookup to a Lookup File Set loads a virtual Data Set first? If not, again little impact on memory.

That's another of the variables that would affect your decision.
