can be achieved in two ways: – Use Snapshots (filesnapshotting) to keep data in-memory written to disk; – Log each update (APPEND-ONLY) using a log method similar to MySQL. Redis supports synchronizing data to multiple slave libraries, which is useful for improving read performance, and master-slave replication allows multiple slave servers to have the same database copy as master server. Configuring the slave server is simple, just add the configura

First, you need to configure the Redis conf file, which involves the LRU related configuration A total of three are:
MaxMemory, sets the maximum memory size that Redis uses to hold data, and once it exceeds this memory size, it immediately cleans up some of the data using the LRU algorithm
Maxmemory-policy, you can set the memory to the maximum idle, what policy to take to handle(1) Noeviction:
In addition to memcache, a commonly used php operation class library, we may also be very familiar with memory cache, which is redis. we will share this php technical article with you, this is about how to use php to operate the redis memory cache tool library. Php redis
Memcached and Redis have the same point: All are stored in the form of key-value pairs to store the data, popular speaking is a big HashtableThe cached data is present in the content Key-valueDifferent points:Memcached:1, a key corresponding value must be serialized through the client into a binary stream storage byte[] (disadvantage, because the serialization of deserialization consumes a large CPU)2, a key corresponding to the maximum value can only
Distributed caching, can solve the single server memory can not be unlimited expansion of the bottleneck. In the application of distributed caching, multiple client contention issues are encountered. This time, need to use a distributed lock, the client has access to the lock to operate permissions.
Memcached and Redis are common distributed cache-building schemes, and the following are examples of implemen
Tags: Understanding data ring Why increase access speed disk resolution list first of all, we know that MySQL is persistent storage, stored in the disk, retrieval, will involve a certain IO, in order to solve the bottleneck, so there is a cache, such as the current use of the most memcached (referred to as MC). 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
