Subject RE: Re: Use of mod_rewrite on Perl sections
Date Wed, 01 Mar 2000 10:24:22 GMT
I am pleased to say that, having written a Tie:DxHash module 
(allowing duplicate keys and preserving insertion order), the problem 
was solved.  Thanks to all who offered advice.  Once I have cleaned 
up, documented and packaged the module, I will submit it to CPAN.

Maybe you need a Tie::BTREEHash?  (I just invented it, but I've been
thinking about it for a while.)

The thinking behind it is this: I have been using a small, fast, solid
BTREE/ISAM package (from SoftFocus, Canada) for about 15 years.  To my
way of thinking it's the way to go if you want keyed access to, say,
between 20,000 records (my customer file) and half a million records
(my invoice file) where a flat file solution is starting to groan but
you don't want the overhead of a full-blown database.

It should be relatively easy to harness it, I have a harness I wrote
when SoftFocus changed all the calling conventions and broke all my
code (grr...).  It's all written in C BTW.

Now I'm sure that somebody on the list is going to tell me that it's
already been done (they usually do that when I have an idea:) which is
why I'm posting this.
