Re^7: tying a hash from a big dictionary

Ouch. They must be some long phrases. Even if you're on a 32-bit OS whereby only 2GB or 3GB of that memory is available to the process.

You're definitely going to need to use external storage.

I used BerkeleyDB with some success for a bit under 32-bit Perl. Though it can take quite a while for the initial building of a large DB, once built the access/retrieval times are about as good as I've ever seen for a disk-based system. You do need to pay some attention to the various configuration parameters to get the best out of it. Look for the BerkeleyDB tuning guide on-line as the module pod is pretty light on tuning.

If you find yourself up against it performance-wise then the object interface is marginally quicker than the tied interface, but much less nice to use. If it is a reference-only DB, sticking (the pre-built) DB file on a cheap SSD, or even a fast thumbdrive, can do wonders for access times.

Just wish I could get it to build for my 64-bit system :(

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
