Django - alert when memcached is down
Is there some ready-made addon that alerts admins about memcached instance being inaccessible from a Django application? I don't mean here monitoring memcached daemon itself, but something that checks if my Django app benefits from caching. My basic idea is to check if cache.get that follow cache.set actually returns something, and if n...

How can I force Rails (2.3.x) MemCacheStore to read a value from the server?
Long story short: I have some controller logic that requests a value from the cache X times, expecting to get a different value on subsequent requests if it has in fact changed on the cache server in between cache requests (this is all within the context of a single HTTP request). However it seems that Rails MemCacheStore wraps itself w...
pagination and memcached in rails
What's the best way to cache a paginated result set with rails and memcached. For example posts controller def index @posts = Rails.cache.fetch('all_posts') do Post.paginate(:conditions => ['xx = ?', yy], :include => [:author], :page => params[:page], :order => 'created_at DESC') end end This obviously doesn't work when the params[:...
Can a Memcached daemon ever free() unused memory, without terminating the process?
I believe that you can't force a running Memcached instance to de-allocate memory, short of terminating that Memcached instance (and freeing all of the memory it held). Does anyone know of a definitive piece of documentation, or even a mailing list or blog posting from a reliable source, that can confirm or deny this impression? As I un...

What to use instead of memcache
I'm using memcache for caching (obviously) which is great. But I'm also using it as a cross-request/process data store. For instance I have a web chat on one of my pages and I use memcache to store the list of online users in it. Works great but it bothers me that if I have to flush the whole memcache server (for whatever reason) I loose...

memcached scalability and efficient voting stats
How scalable is memcache in an enviornment where a cache is potentially getting expired every second. In fact, my question is not just about scalability of memcached but about situations where a model is continuously changing and the best way to scale that type of environment. One might say, why cache if the cache is getting expired ever...

Porting SQL results into memcached
