First, the user accesses the MC, if not hit, to access MySQL, and then like memory and hard disk, the data copied to the MC part of the

I. Introduction to RedisRedis is an open-source (BSD-licensed), in-memory data structure storage system that can be used as a database, cache, and message middleware. It supports multiple types of data structures such as string (strings), hash (hashes), list (lists), set (sets), ordered set (sorted sets) with Range query, bitmaps, h Yperloglogs and geo-spatial (geospatial) Index RADIUS query. Redis has bui

The queue used to generate the cache is written to nearly queues every 20 minutes, but the cache generation is not so fast. as a result, the queue accumulates more and more, and the memory usage is getting bigger and bigger. do you have any solutions?

When using Redis, there are times when there is a lot of data back, and the same classification, the same IDCan be set using Hset, so there is a large class and a small classification and a value compositionHowever, Hset cannot set the expiration timeExpiration time can only be set on set 1 Adding cache to REDIS 2 jedisclient.set (Redis_i

The idea of using Redis as a cache is to configure the interceptor in the spring project, make slices on the service layer, and intercept on methods such as FINDXXX or getxxx to determine if caching is possible.1.
