I don't really know if the list is the right place to do this, but attached is a hack of what I had for my Cached FastMmap module converted over to CHI. I've tested the basic functionality, but don't know if this is really the correct way to implement it. I like the idea of CHI and would like to be able to do something along the lines of selecting the cache driver I want to use with my script that starts my process. In one script I may want to set my Rose Objects to use a Memory cache, but in my FastCGI or modperl process I may want it to use FastMmap. I keep thinking an environment variable of some sort, but there has to be a better way, right? -Kevin

I wanted to test using FastMmap because I want my application to use the same cache across different processes. So far it's been a success and I've now been working on trying to make it more generic. I'd be willing to help with coming up with a module that does this, I would definitely have an interest for it. Instead of using Cache::FastMmap directly, how about using CHI: http://search.cpan.org/~jswartz/CHI/ That would let you experiment with different backends without changing your code. I haven't tried it yet but I've heard good things. -sam
#### Within Metadata Class ###
### By default there will be namespace for every

### FastMmap file will need to be created for each one.
### Keys are set in a way that we could use a global namespace
### if we wanted to here, so only one FastMmap file is created.
