What I am not sure about is the maximum size. Sort::Maker appeared to be the closest match to the OP needs of the namespace you refer to, but even that didn't make it clear enough to me what the filesize limits are for the OP's particular key definitions for a particular CPAN module. The OP is partly at fault there for not giving that much info in regard to the distribution of information - two example records ain't much to go on.
