Memcached is a set of memory cache system or software, used in dynamic application system to cache database data, reduce database access pressure, achieve performance improvement purposes1, commonly used in the enterprise database cache2, as a storage for session data sharing between cluster architecture node application serversMemcached is to store data by pre-allocating the specified memory space, Java, PHP applications, and more than 1000 single my

preheat the underlying data and then update it dynamically. Read the cache first, if there is no corresponding data in the cache, then read the database, and then put the read data into the cache.Special Instructions:1. If you encounter the business of high concurrency such as e-commerce, it must be pre-warmed, or other ideas to achieve, for example: seconds to kill just get qualified, and not instantaneous seconds to kill the goods.2. If the data is updated, the cache update is triggered and t

PHP distributed cache memcached familiarity and operations, php cache memcached In the era of the rise of the Internet, all major websites are faced with a big data stream problem. How can we increase website access speeds and reduce database operations? As a PHP developer, we can generally think of static page processing, anti-leeching, accelerated access to CDN content distribution, index creation for mys

. Currently, Internet data is stored in relational databases or key values in two ways. However, these Internet businesses do not belong to these two data types. For example, the relationship between users in the social platform is a list, if you want to store data in a relational database, you need to convert it into a multi-row record format, which has a lot of redundant data, and each row needs to store some duplicate information. If the key value is used for storage, modification and deletio

,auto-sharding and so on. For example, some common document databases are supported Schema-free, directly store JSON format data, and support auto-sharding functions such as MongoDB. In the face of these different types of nosql products, we need to choose the most suitable products according to our business scenarios. Redis is most suitable for all data in-momory scenarios, although Redis also provides t
