As a result of a systematic study of Redis, Redis is used as the data cache in multiple projects in the company, so take advantage of these days to write a demo of the time, here for your own later study notes, if there is wrong place, please tap bricks. The Redis website recommended to Java use a lot of clients: Jedis

different application deployment, and only one database server, this concurrency problem is easily solved. So now let's take a look at whether to move it to the application to avoid adding database servers to the business.For example, there are two application servers and one database server. The idea is to deploy Redis on the database server. When the two servers operate on the concurrent cache or queue,

queue and the cache, and will not cause any troubles in the concurrent environment, because all operations in Redis are atomic operations.As for comment on the two, the good or the bad will be free, the existence is the reason, the best choice is the best.Let's start to play with the queue (distributed) design YY in Redis. Please give me some advice.Scenario:Currently, all projects are deployed on multiple

method, JMeter calls the/bdp/city/rename.json interface:Then look at Redis storage:The cache of the Searchcity method has also been cleaned up, and the caching of the Renamecity method has worked. 7. Precautions The Java object to be cached must implement the Serializable interface , because Spring will serialize the object first into Redis, such as the Com.

a performance bottleneck for a system when the number of requests is high, or when some request processing is slow (such as some large data ordering). There are ways to mitigate even this problem by building multiple Redis instances that are implemented through multiple redis connections. 3. In addition, a single large Redis instance can also increase the diffic

Redis Study Notes (7)-cluster client (jedis) code example, redisjedis In the previous section, I learned how to build a cluster and operate on the redis-cli terminal. However, a more common scenario is to read and write the cluster in the program code, this requires redis-client Support for the cluster mode. Currently,
