memcached

问题 Im trying to find a good way to handle memcache keys for storing, retrieving and updating data to/from the cache layer in a more civilized way. Found this pattern, which looks great, but how do I turn it into a functional part of a PHP application? The Identity Map pattern: http://martinfowler.com/eaaCatalog/identityMap.html Thanks! Update: I have been told about the modified memcache (memcache-tag) that apparently does do a lot of this, but I can't install linux software on my windows

问题 I am facing issue while getting value from cache. java.lang.RuntimeException: java.lang.ClassCastException: com.mycom.admin.domain.User cannot be cast to com.mycom.admin.domain.User Cache Configuration @Configuration @EnableCaching @AutoConfigureAfter(value = { MetricsConfiguration.class, DatabaseConfiguration.class }) @Profile("!" + Constants.SPRING_PROFILE_FAST) public class MemcachedCacheConfiguration extends CachingConfigurerSupport { private final Logger log = LoggerFactory.getLogger

问题 When running pip install pylibmc on Ubuntu, I get the following error: _pylibmcmodule.h:42:36: fatal error: libmemcached/memcached.h: No such file or directory 回答1: sudo apt-get install libmemcached-dev zlib1g-dev 回答2: Zags answer didn't do the trick for me on Ubuntu 13.10. libmemcached-dev had already been installed. I had to also do: sudo apt-get install zlib1g-dev Maybe that will help someone else. 回答3: Install libmemcached using below command sudo apt-get install libmemcached-dev zlib1g

问题 This is from just a single memcached server with around 20M keys (no expiry) and around 2G of data. What's the easiest way to get a dump of all the key/value pairs into a flat file? I first looked at the java net.spy.memcached.MemcachedClient, but this client does not support getting all keys (I think). If I had a list of all keys (which I don't), I could easily use this client to get all of the values. I know I can get all keys using some telnet commands (e.g., telnet localhost 11211; stats

问题 I currently have a huge problem. Two days ago my site running on one server was too much, so I purchased two more and had them clustered (rsync and load balanced). I then start noticing that a user would hit server-1 and then on the next request hit server3 but that their session was still on server1 instead of server3 and they were no longer logged in. I was recommended to use memcache for session stores. My script already uses $_SESSION . Can we get memcache installed and enable session

问题 I am looking for cache server for .NET. What can you suggest? As i know memcached has provider for .net. Is it good enough to use for .net in production? 回答1: AppFabric is another popular solution from Microsoft. 回答2: If you're willing to run your cache server in Linux, you could use Redis, and use the BookSleeve library from .NET, this is what StackOverflow uses http://code.google.com/p/booksleeve/ 回答3: Scale Out State Server is an excellent solution. It's not free, but for large-scale

问题 I'm thinking about the best way to create a cache layer in front or as first layer for GET requests to my RESTful API (written in Ruby). Not every request can be cached, because even for some GET requests the API has to validate the requesting user / application. That means I need to configure which request is cacheable and how long each cached answer is valid. For a few cases I need a very short expiration time of e.g. 15s and below. And I should be able to let cache entries expire by the

问题 I wish to clear the entire second level cache in NHibernate via code. Is there a way to do this which is independent of the cache provider being used? (we have customers using both memcache and syscache within the same application). We wish to clear the entire cache because of changes external to the database may have occurred (and we have no guarantees re: which tables/entities were affected, so we have to assume the worst). 回答1: This should do: sessionFactory.EvictQueries(); foreach (var

问题 We use memcache basically as an after thought to just cache query results. Invalidation is a nightmare due to the way it was implemented. We since learned some techniques with memcache thru reading the mailing list, for example the trick to allow group invalidation of a bunch of keys. For those who know it, skip the next paragraph.. For those who don't know and are interested, the trick is adding a sequence number to your keys and storing that sequence number in memcache. Then every time
