Subject: Shared hashtable
From: stuttle@gmail.com (Stut)

Hi all,

I'm being asked about the possibility of creating an extension that will 
cache some data from a MySQL DB in-memory. I've been reading various 
online resources regarding building extensions and cannot find an answer 
to the following question... Is there a way to create a hashtable in the 
extension which will be available to all of the Apache children without 
resorting to shared memory?

It's important that only one instance of the data exists for two 
reasons... 1) It's a fairly large amount of data and 2) it will change 
as the application runs. I've created a small test extension using 
MODULE_GLOBALS the results of which suggest that these variables are per 
process. I'm just looking for some confirmation that shared memory is 
the way to go before I jump down that particular black hole.

TIA.
