about RedisRedis is one of the NoSQL (no only SQL, non-relational) databases that NoSQL stores data in the form of Key-value. The current mainstream distributed cache technology has REDIS,MEMCACHED,SSDB,MONGODB and so on. Redis can be understood as a caching technique, because its data is cached from it, and it can be understood as a database, because

Redis for beginners (3) -- using Redis as the cache of Mysql database, redismysql
After the Mysql result set is cached in the Redis string or hash structure, we are faced with a new problem, such as what these strings or hash names are, that is, how to determine their keys. Because the rows corresponding to these data

Two problems must be solved when Redis is used as the Mysql database cache. First, determine the data structure used to store data from Mysql. After determining the data structure, consider the id
volume of traffic, we can also combine the above two improved architectures, both read-write separated relational databases, and high-speed access to the cache service.The premise of the above cache server architecture is that getting data from a cache server is much more efficient than getting it from a relational database. Otherwise, the

first, and after close () calls the Close () method, which is equivalent to generating a new session instance, so we do not have to manually close the session (), It is also not possible to use MyBatis's first-level cache, which means that MyBatis's first-level cache does not work in spring.
Therefore, we generally implement the MyBatis level two cache in the pr
Two problems must be solved when Redis is used as the Mysql database cache. First, determine the data structure used to store data from Mysql. After determining the data structure, consider the identifier used as the key of the data structure. Intuitively, data in Mysql is stored by table. In a more microscopic view, these tables are stored by row. Each execution of selec
Two problems must be solved when
execute the appropriate SQL statement, query the corresponding result set in MySQL, and then follow the above method to store each row in the result set as a string or hash into Redis. The code for finding the corresponding result set in Redis is as follows:The function queries the corresponding result set in Redis based on the SQL statement and returns the key
briefly summarized: first, sorting increases the load on the database and is difficult to support highly concurrent applications. Second, sorting in the cache will not encounter the problem of table locking. Redis just provides the sorting function, so that we can conveniently sort the cache.
