Large hashes of hashes
|
|
| jrpfinch 2007-02-15, 7:00 pm |
| I have written a program that constructs a large hash of hashes (of
hashes.... several layers deep) and manipulates it in several ways.
Currently it becomes no larger than 20Mb on a machine that has about
500-600Mb RAM spare.
One day it could possibly exceed the size of the RAM - if this
happens, is there a way to easily adapt the script to use some sort of
virtual memory, or will I have to rewrite the program to use some kind
of database.
I am running it on Solaris 9 and 10 boxes.
Cheers
Jon

That's the purview of the operating system. The OS should
automagically page out if necessary (provided sufficient virtual
resources are available).

That might not be a bad idea, regardless of the memory situation.
Nothing manages massive amounts of data as well as a good database.

The best way to get a good answer is to ask a good question.
