redis and memcached

The widely used distributed cache Redis and memcached support the addition and subtraction of integer value values, which corresponds to the incr and DECR commands in the specific command.INCR/DECR is an atomic operation (Memcached 1.2.4 and later added/redis), which is widely used in counters and speed limiters.distri

Memcached is a high-performance distributed memory object caching system for dynamic Web applications to mitigate database load. It provides a dynamic, database-driven site speed by caching data and objects in memory to reduce the number of times the database is read.Memcached is based on a hashmap that stores key/value pairs.Redis is a key-value storage system, similar to memcached. However, it supports st

Memcached is a high-performance distributed memory object caching system for dynamic Web applications to reduce database load. It reduces the number of database visits by caching database query results in memory to improve the speed and scalability of dynamic Web applications. Redis is a key-value storage system and is a high-performance key-value database. Caching mechanisms are often an important starting

1. Network I/O model Memcached is a multi-thread, non-blocking I/O multiplexing network model. It is divided into the listening main line and the worker subthread. The listening thread listens to network connections. After receiving the request, it passes the connection description pipe to the worker thread, for read/write Io, the network layer uses the libevent encapsulated event library. The multi-threaded model can play a multi-core role, but int

Similarities between the twoBoth memcached and Redis belong to in-memory , key- value data storage scenarios. They all belong to the NoSQL family in the data management solution and are based on the same key-value data model. Both sides choose to keep all the data in memory, which naturally makes them a very ideal buffer layer implementation scheme. From a performance perspective, the two types of data stor
