Memcached is also a distributed memory caching system. For every master node there are two slave nodes for redundancy, therefore, if the master fails, then the system automatically promotes one of the slaves as the new master. Redis, which means Remote Dictionary Server, was created in 2009 by Salvatore Sanfilippo, to improve the scalability of the web log analyzer that his Italian startup was building. Memcached is easily scaled vertically, as it is multithreaded. Redis uses only single nuclei while Memcached uses multiple nuclei. Supported languages include Java, Python, PHP, C, C++, C#, JavaScript, Node.js, Ruby, Go and many others. It uses an allocation mechanism called Slab, which segments the allocated memory into chunks of different sizes, and stores key-value data records of the corresponding size. Amazon ElastiCache supports the Redis and Memcached cache engines. The first prototype was written in Tcl and later transcripted to C. When Sanfilippo decided to open source the project it then started to get some traction. Memcached: Supports only simple key-value pair structure. Both Redis and Memcached support sub-millisecond response times. This allows to mitigate the need to do it at an applicational level. 3. New DB-Engines Ranking shows the popularity of database management systems 3 October 2012, Matthias Gelbmann, Paul Andlinger. Redis and Memcached are both popular in-memory data storage systems. Redis allows you to execute transactional Lua scripts. The AOF log is better if data loss is not acceptable at all, as it can be updated at every command. At Imaginary Cloud, we simplify complex systems, delivering interfaces that users love. By storing data in-memory they can read data more quickly than disk based databases.
