问题 First, my purpose is when the user close the browser then the user session data should expire. Now the problem is that, my Server requires memcached to work properly. So, I want to delete that specific user session from memcached who has closed his browser. I dont want to clear all memcached so that the remaining users' session should still exist. 回答1: In Memcached there is no way to list all keys in a specific namespace unless you want to use some workarounds, and I don't recommend you in

Log visits in shared memory

问题 I'm trying to find best way to log visits using PHP. Right now I have about 3000 request per second and I write each visit to CSV file. I was wondering is it faster to log each visit in memory somehow and then dump it to CSV file after 100 000 records? I've checked shmop apc and memcache so far but can't find proper solution. 回答1: The best way is to use Lua with shared memory to store log entries, then create a timer which checks the size of logged entries every X seconds and uses a co-socket

What is the best optimization technique for a wildcard search through 100,000 records in sql table

由 佐手、 提交于 2019-12-22 09:57:47
问题 I am working on an ASP.NET MVC application. This application is used by 200 users. These users constantly (every 5 mins) search for an item from the list of 100,000 items (this list is going to increase every month by 1-2 %). This list of 100,000 items are stored in a SQL Server table. The search is a wildcard search eg: Select itemCode, itemName, ItemDesc from tblItems Where itemName like '%SearchWord%' The searching needs to really fast since the main business relies on searching and

How to cache files over 1MB with rack/cache on Heroku?

由 时光怂恿深爱的人放手 提交于 2019-12-22 04:46:21
问题 I'm using a combination of Dragonfly and rack/cache hosted on Heroku. I'm using Dragonfly for uploaded assets. Thumbnails are processed on-the-fly and stored in rack/cache for fast delivery from memcached (via the Memcachier addon). Regular static assets are also cached in memcached via rack/cache. My problem is that any uploaded files over 1MB are causing a 500 error in my application. 2013-07-15T10:38:27.040992+00:00 app[web.1]: DalliError: Value too large, memcached can only store 1048576

PHP - Memcache - HTML Caching

由 烈酒焚心 提交于 2019-12-22 00:45:25
问题 I would like to create a caching system that will bypass some mechanisms in order to improve the performance. I have some examples: 1-) I have a dynamic PHP page that is updated every hour. The page content is same for every user. So in this case I can either: a) create an HTML page, and that page can be generated every hour. In this case I would like to bypass PHP, so there should be a static page and if the database is updated, a new HTML file will be generated. How can I do this? I can

memcached 源码阅读笔记

阅读 memcached 最好有 libevent 基础, memcached 是基于 libevent 构建起来的. 通由 libevent 提供的事件驱动机制触发 memcached 中的 IO 事件. 个人认为, 阅读源码的起初最忌钻牛角尖, 如头文件里天花乱坠的结构体到底有什么用. 源文件里稀里哗啦的函数是做什么的. 刚开始并没必要事无巨细弄清楚头文件每个类型定义的具体用途; 很可能那些是不紧要的工具函数, 知道他的功能和用法就没他事了. 来看 memcached 内部做了什么事情. memcached 是用 c 语言实现, 必须有一个入口函数 main() , memcached 的生命从这里开始. 初始化过程 建立并初始化 main_base, 即主线程的事件中心, 这是 libevent 里面的概念, 可以把它理解为事件分发中心. 建立并初始化 memcached 内部容器数据结构. 建立并初始化空闲连接结构体数组. 建立并初始化线程结构数组, 指定每个线程的入口函数是 worker_libevent() , 并创建工作线程. 从 worder_libevent() 的实现来看, 工作线程都会调用 event_base_loop() 进入自己的事件循环. 根据 memcached 配置, 开启以下两种服务模式中的一种: 以 UNIX 域套接字的方式接受客户的请求 以

问题 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
