flush redis cache

caches the user data and In addition to caching PHP code, APC can also be used to cache user data, but because the APC capacity is very small, so the cached data is best for those long time unchanged data, unchanged units should be in the space units. So if the data is changing very frequently and the amount of data is large, then do not use APC, you can use Memcache or Redis.

Baidu definition: Redis is a key-value storage system. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered set), and hash (hash type), in order to ensure efficiency, The data is cached in memory.The difference is that Redis periodically writes the updated data to disk or writes the modified operation to the appended r

Redis is a high-performance Key-value database. The emergence of Redis, to a large extent, compensates for the lack of memcached such keyvalue storage, in some cases can be a good complement to the relational database. It provides the python,ruby,erlang,php client, which is very convenient to use.Now Redis has released the 3.0 version, formally supporting the dis

In today's concurrent environment, it is best to cache queries for large volumes of data using Redis to build clusters(Personal like Redis, memcache not cold)Redis is a cluster feature added after 3.0, very powerfulThere should be at least three nodes in the cluster, with one backup node per node. It's going to take at

In the process of using Redis to cache data, the idea of designing a cache is as follows: When the data is fetched, the data is fetched from the cache, and if the obtained data is empty, the database is queried and the queried data is cached to Redis before the data is retu

Each select () query automatically executes opensession () and calls the close () method after Close (), which is equivalent to generating a new session instance, so we don't have to manually turn off this session (). Of course, you cannot use a mybatis cache, meaning that a mybatis cache is not useful in spring. Therefore, we generally implement the MyBatis level two

Abstract: mainly for the DAO layer of some database query operation, the data is not strong real-time, directly into the cache. When it is in the cache, the data in the cache is used. Such a method is eventually implemented using only one annotation. For the previous Hibernate level two cache use, it is quite strange.

In MyBatis, developers are allowed to customize their own caches, and this article uses Redis as a level two cache for MyBatis. Defining a Level Two cache in MyBatis requires the following configuration:1, mybatis support the total switch of level two cache: Global configuration variable parameter "Cacheenabled=true"2.
