Hi Everyone. The code I have below might attempt to store up to a million keys on any given day and it runs out of memory. How can I store a huge amount of data while using a minimal amount of memory? It reads several files with the following format:

some_name 3 19
A_name 9 2 

while(<IN>){
                @tmp = split;
                $key = shift @tmp;
                $cache{$key}[0] += $tmp[0];
                $cache{$key}[1] += $tmp[1];
        }
        close IN;

foreach (keys %cache){
       print OUT $_," ",join( " ", @{$cache{$_}}), "\n";
}
close OUT;
