I am thinking like JavaBeans. Here is what I have going on:
I have a series of rather database intensive queries that I would like some class to cache and provide access for page loads. I don't care how the information is stored, but I am trying to minimize the database call down to only once an hour at the most.
The trick is that I just want the data - like a quazi-db table in memory...
Is there something like that I should look at? Somewhere in PEAR?
You may want to try this generic data caching class. I use precisely for what you want, cache the contents of pages that are built with data from databases that does not change frequently and would consume too much database resources to retrieve all the time.
It caches the data in files and uses readers and writers locking to assure robustness and integrity of data caches preventing that simultaneous accesses corrupt the stored data.
If you need to cache data for many pages or eventually different data for the same pages but for different users like I have, caching all data in memory is not wise. The problem is that allocating too much memory may compromise the stability and performance of your system during moments when memory a lot of real memory is needed.
Caching a lot of pages or generic in disk is a good compromise because the modern operating systems use the free real memory for buffers that are relased on demand as your system requires it.
