I'm new to both memcached & sharding. I gone though some articles on both. I need to implement both in my application. Articles I'd gone through were good but none of them gave me how to use these technologies. Anyone who can suggest me the links from which I can actually configure them and run the samples. I want to implement memca...
I wanna know if there is any loadbalance/failover plan for memcache. I'm using JAVA client. I knew some client implementions can talk with multi memcache servers, but how about loadbalance? ...
I am using memcache for cacheing objects, but would like to add in addition an opcode accelerator like APC. Since they both involve cacheing, I am not sure if they will be "stepping on each others toes", i.e. I am not sure if memcache is already an OP code accelerator. Can someone clarify? I would like to use them both - bit for differ...

Hello, do you have any ideas of how to store comments in memcache? Let's imagine that I'm having image with a lot of comments for it. All comments are separated in pages. User can define number of comments per page in his profile. How should I store comments in memecache? Should I store all comment's IDs in one memcache key or should ...
The title asks it all. The content on the site I'm building wont change very quickly at all and so Memcache could potentially store data for months except for when I put up an update. Is there a way to make it clear the cache every time I deploy the site? I'm using the Python runtime. Update 1 Using jldupont's answer I put the followin...
Hi, Okies, I have successfully installed the XAMPP and added virtual hosts and am able to make database calls and stuff. The problem I am facing is while trying to enable the memcache module.

So I tried: root@xyz:~# killall memcached root@xyz:~# /etc/init.d/memcached stop Stopping memcached: memcached. root@xyz:~# memcached -d -m 128 -l 127.0.0.1 -p 11211 -vv -u www-data bind(): Address already in use failed to listen root@xyz:~# memcac...
I have 2 servers running tokyo cabinet in a cluster (2 hard drives so 4 instances of Tokyo Cabinet). if it's just one instance of tokyo cabinet it's fairly straight forward to use php memcache protocol to communicate. My question is how do you connect php if it's cluster? Option 1: $memcache->connect('memcache_host', 11211); Using thi...
I've been at this for days. I have configure my web/app config to use the second level cache with a Memcached server and the provider from NHContrib. I don't get any exceptions yet in testing I see that it does not use the cache for my queries that I have set cacheable = true. If I switch the provider to the NHibernate.Cache.HashtableCac...
I been using cmemcache + memcache for a while with positive results. However cmemcache lately not tagging along well and I also found that it's now recommended. I have now installed python-memcached and its working well. As I have decided to change would like to try some other cache back end any recommendation. I have also came across...
I'm implementing a PHP script which will need some caching capabilities. I'm trying to determine which caching strategy to use for user data assuming that the script is running on a single server. I'm probably looking at about 50k different keys. The data for each key is not very big - in most cases less than 5kb. I have implemented a ...
does any body have any info/links as to how to integrate a cookie based session system? i've used file/mysql, and am currently using memcached. i wanted to play with apc sessions, but thought i'd give a go at cookies, only i don't know much about it. i imagine i'd have to write my own session handler class? ...
If launching as root like this: memcached -c 5000 ... do I need my startup script to look like this: ulimit -n 5000 memcached -c 5000 ... Or will memcached set the max open files automatically? ...
I'm looking for information on things like ehcache and other alternatives to memcached for a project that will likely involve 3-4 webservers and something like 2-10 million distributed objects that need to be available to all servers. Specifically, I'm trying to understand how other systems distribute data, whether or not memcached is u...
I need to acccess memcache from my C++ application. In oerder to avoid reinventing the engine, I have been searching for existing libraries. Suprisingly, there are very few of them around (for the most part, interfacing is done in C not C++). However, I have found two - both of which have very early version numbers, and appear to be "de...
I have a rails app that is communicating with some java services over JMS. I'm caching a few of these objects in memcached on the rails side like so: @my_objects = MEMCACHE["some_key"] || @service.retrieve_objects MEMCACHE.set("some_key",@my_objects) if MEMCACHE["some_key"].nil? where MEMCACHE is MEMCACHE = MemCache.new(['localhost'...
I need to implement cache for SQL queries. Say we have "SELECT id,aa,bb FROM table1 WHERE aa>1 and bb=12;" -- we want it to be cached. Also, it may be "SELECT id,aa,bb FROM table1 WHERE aa>25 and bb=11;" And can be "SELECT id,aa,bb FROM table2;" of course. Not a big deal -- what really is a question is how to expire cache values better...
I am designing a website implementation. There are two web server machines and we would like out-of-process global cache provided by Memcached. I envisage placing memcached on two separate boxes whose sole purpose is to serve the global data cache. Would such an implementation be considered "typical" and would the term "cache server" be...
