memcached

I notice that in my production enviornment (where I have memcached implemented) in see a cache-control - max-age header in firebug, anytime I am looking at an index page (posts for example). Cache-Control max-age=315360000 In my dev environment that header looks like following. Cache-Contro private, max-age=0, must-revalidate As far as I know I have not done anything special with my nginx.conf file to specify max age for regular content, I do have expires-max set for css, jpg etc. here is my nginx.conf file.. http://pastie.org/1167080 So why is this cache-control is being set? How can I

Is there any chance of getting a garbled value for a key in memcached in multi thread environment?. If so how to avoid it with minimal time of synchronization?. Using Java client to access memcached server No. Memcache will return a value that somebody wrote previously, and not a garbled value. If you get/modify/put you have no guarantee that the put applies to the same value as the get. Use the cas (compare and set) operation if you need to synchronize. 来源： https://stackoverflow.com/questions/6611799/is-memcached-get-and-put-methods-are-thread-safe

Below is a function I found about a year ago that is supposed to put a lock on a memcache key so you can update it's value without any trouble of 2 request trying to update the key at the same time. It is pretty basic but I could use a little help in figuring out how to use it 100%. The part I am not sure about is where it passes in a $updateFunction which is then passed to ** call_user_func($updateFunction, $data); // update data I have never used the call_user_func() before. Based on this code could some one show me a basic example of what a function that it calls could look like (without

There seem to be quite a few promising packages with no clear suggestions on which is the fastest,scalable and which is more memory efficient. npm install memoizee npm install memcached lru-cache npm install memory-cache npm install node-cache Any reliable sources of information/personal experience with these would help. So the basic usage is for simple key:value store. Just need to know if the underlying architecture of these different stores is similar/different and if different then which would be scalable. [Also which of these is used by express-session to implement the MemoryStore .] The

In the past month, our Java Google App Engine Standard Web App started getting strange errors at seemingly random times (see stack trace below). Around this time we made the following changes: Switch from Java7 runtime to Java8/Jetty9 runtime (which allowed us more flexibility in linking to a 3rd party payments library). Switch to deploying with the Google Cloud SDK, instead of the separate Google App Engine SDK. Yesterday we experienced 3 periods with errors. One of these occurred from 0530PST to about 0600PST on Feb 28. Suddenly all attempts to load from the database started failing: com
