Hei, I wrote the little depcached variation on top of memcached. The main purpose of depcached is to
I created depcached for a number of reasons: 1. Add dependencies between keys, to help the hardest problem of caching - cache invalidation; 2. Hierarchical cache keys so a cache can be used by different sites at the same time; 3. In our use the slab allocator gave us out of memory problems; 4. Added a garbage collector to actively purge invalidated cache entries; 5. Added queues, but we really didn't use them. I am about to start with a rewrite to address some problems we saw in production. The queues were literally hacked upon it, and I want to completely redo that part. I think that the queues are something completely independent from the caching part and the only reason to merge them into a memcached alike is to prevent having yet another connection and service on your webservers. Any suggestions for a queue part are welcome. - Marc Worrell
