Caching system like memcached but where I need to list what is in the cache

Question

What's the best caching system/daemon that supports get, put, delete and list (memcached, I think, doesn't support list)

An example

I would like to use memcached for my caching solution but I'm stuck with the application design that I currently have which is that I cache the following 3 URLs I need to always have different cache keys. That stops me from just declaring a list of URL params with which I could generate a cache item for.

• /badappdesign?iod=3
• /badappdesign?iod=3&h=23
• /badappdesign?iod=3&dsfj=435&dasv=342

In this instance iod=3 has changed so I need to clear all the keys that contain iod=3

I currently cache to a db and have to do a fairly expensive like '%iod=3%'

what can help?

Answer 1

Pull the '3' out of iod=3 and stick that into an integer column and index on that? That will be drastically less expensive.

Answer 2
