With the development of Redis, more and more architectures have replaced memcached as the cache server, which has several outstanding features:1. In addition to hash, sorted Set, list and other data structures are provided.2. Can be persisted to disk3. Support Cluster (3.0)It has the same performance and memcached, and with the popular other components (such as queues) will also use
Redis believe that everyone is familiar with, and memcached is a high-performance Key-value database, as to what is the cache server, degrees Niang have a very clear introduction, I do not introduce here.
So what are we going to do with a cache server in general? It's not exactly what you need. Oh, in general, it is necessary to read a field frequently when you
In the previous article we analyzed the first level cache, level two cache related source code and basic principles, today we share the MyBatis level two cache and Redis combination, of course MyBatis two cache can also and Ehcache, Memcache, Oscache, Hazelcast used in combi
Label:In traditional projects, we often use caching to optimize database reads, such as in Java, where we take advantage of Spring's AOP capabilities to increase caching operations before reading and writing databases. Similar problems still exist in node and MongoDB projects, this article refers to the Mongoose-redis-cache plugin. Https://github.com/conancat/mongoose-r
First, the purpose of caching the home page is not to improve performance, but to reduce database access pressure and effectively delay the arrival of database I/O bottlenecks. There are many ways to implement the home page cache, but since Redis is used in the project to cache database reads and writes, you can also cache
In brief, writing this article is a summary of your recent work. I hope it will be helpful and a little bit of accumulation.
I. Why redis?
Redis is used as the cache in the project and memcache is not yet used. There are two main considerations:
1. Support for redis's rich data structures, its hash, list, set, and function-rich strings can be of great help to act

No more nonsense.Next idea: using AOP annotations, in the service implementation class add the need to use the Redis method, when each request came over to intercept it, if the query is from Redis get key, if it is update delete key, Prevent dirty data or historical data from appearing.
