Hi! Just like the title, how would a multiget from memcache look like? Is this the correct way of utilizing multiget? : $memcache_obj = new Memcache; $memcache_obj->connect('memcache_host', 11211); $var = $memcache_obj->get(Array('some_key', 'second_key')); Thanks UPDATE: anyone looking to do the same, check out this addition as w...
Is there support for sliding expiration in the GAE MemcacheService? I can do a crude implementation where following every get() I do a put(). This will effectively reset the expiration time but this obviously is not an efficient solution. Any pointers on how I can implement this more efficiently? Thanks, Keyur ...

Hi all, I'm studying how to use caching in Heroku for my Rails app. HTTP cache powered by Varnish is superb and I'll use it in all pages without user info but I also want to use a kind of ActiveRecord caching with Memcached using "high livel" plugins such as cache_fu or cache-money...but it seems that Heroku supports only the memcached g...
Looking at http://www.nearmap.com/, Just wondering if you can approximate how much storage is needed to store the images? (NearMap’s monthly city PhotoMaps are captured at 3cm, 5cm, 7.5cm, or 10cm resolution) And what kind of systems/architecture is suitable to deliver those data/images? (say you are not Google, and want to implement t...
The Google App Engine memcache documentation states that the time parameter of memcache.set() is an "Optional expiration time, either relative number of seconds from current time (up to 1 month), or an absolute Unix epoch time." So I tried to set a value for 30 days, which according to Google is 2 592 000 seconds. However, I highly sus...
Hi everyone, I am setting up a new web app that will on the client side feature a multi-memcached server environment for reliability and performance.

I understand the need for a function like DB_Get_Cached("sql string") that hashes the SQL in order to perform a lookup in memcached for the existence of the data. function DB_Get_Cached(string SQL) data = memcache_get_data(md5(SQL)) if (!data) return DB_Get(SQL) end if end function What is a good method to expand this to handle ...
I am concerned about how and when to check for conditions that warrant invalidating data in the cache. I'm thinking in terms of e-commerce product listing or user-profile information. Should this be done with a separate service that runs periodically that checks for old or changed data? Should we rely on database triggers to let us kn...
I have a site with about 150K pages in its sitemap. I'm using the sitemap index generator to make the sitemaps, but really, I need a way of caching it, because building the 150 sitemaps of 1,000 links each is brutal on my server.[1] I COULD cache each of these sitemap pages with memcached, which is what I'm using elsewhere on the site.....

I am rewriting an existing Ruby Gem to include caching. This is for a gem that is relatively commonly used, and accesses a large amount of static data on a web service. Currently, I have a small number of gem users doing a large number of accesses to the service that under normal conditions would be swamping / downing the service, and ...
