[Zope-PAS] Re: RFC: PAS caching

[Jens Vagelpohl]

After considering the comments so far and taking a closer look at the 
RAMCacheManager I have come up with an idea along the lines of Tres' 
suggestion:

- Inside the PAS instance it is possible to create RAM Cache Manager 
objects
- Plugins for which caching makes sense mix in the ZCacheable mixin 
class, and thus become "registerable" with these cache managers

This solution leverages the existing cache manager architecture which 
has been around for a long time and seems to offer enough flexibility. 
It also satisfies my pet peeve of plugins not having to know about or 
talk to the central PAS instance.

The needed changes would include...

- Changing PAS to allow creation of RAM cache managers
- Changing plugins to mix in ZCacheable and making use of the 
appropriate ZCacheable API when it comes to 
retrieving/changing/inserting data

Does that sound like a good idea?
