Memcached does not natively support disk dump. ![]() However, you can customize the snapshotting features in nf file.Ĭheck our tutorial on Redis persistence to explore further. Redis natively supports snapshotting by saving a snapshot of your datasets to a disk in binary file. #XOJO DELETE CACHE PATCH#However, you can implement data replication using patch tools such as Persistence/Snapshots Memcached does not natively support replication. The replication will create exact copies of the master instance regardless of what happens to the master. Redis offers a simple master-slave replication implementation. Memcached supports both TCP and UDP protocols. Redis uses TCP connection protocol or Unix-like sockets with no support for UDP. Memcached uses telnet to connect and manage your server. Redis provides you with a built-in CLI utility to access and manage your databases and Redis server. #XOJO DELETE CACHE CODE#This makes it very easy to learn and use.Īlthough Memcached is general and relatively documented, you may need to dig into the source code to implement custom features. Redis is very well documentation and has a large community behind it. On the other hand, Memcached is limited to the LRU eviction policy. Redis supports a collection of eviction policies that can be customized according to your needs.Ĭheck our tutorial on Redis eviction policies to learn more. However, Redis scales well horizontally while Memcached benefits well on vertical scalability Eviction Policy Scalabilityīoth Redis and Memcached allow you to scale as your data grows. Redis and Memcached allow you to clear cache using the FLUSHALL or FLUSHDB and FLUSH_ALL commands. Since both Redis and Memcached are in-memory databases, they provide sub-milliseconds latency. Data Partitioningīoth Redis and Memcached support the distribution of data across various nodes. However, Redis is single-threaded while Memcached is multi-threaded. Architectureīoth Redis and Memcached follow a client-server architecture. This makes it easy to use and uses less memory overhead than Redis. Memcached, on the other hand, supports plain binary strings. Redis also allows you to perform automatic operations such as appending to strings, calculating set union, difference, intersection, etc., appending an element to a list, etc. Redis has multiple data structures, which are very suitable for many needs. Although there is no official release of Memcached for Windows, you can find Cygwin implementations of the database or compile it for your platform. Memcached is written in ANSI C but cross-platform. Windows support is not yet available as of writing this tutorial. Redis is supported in Linux, BSD, and OSX systems. Redis is written in ANSI C and works in all POSIX systems. It was developed in 2004 by Brad Fitzpatrick and is now used by popular applications such as Twitter, Facebook, Youtube, Instagram, Udemy, Slack, etc. It is used to provide a caching mechanism for applications but acts generically. ![]() Memcached is defined as a free, open-source, and high-performance in-memory database. It was developed in 2009 by Salvatore Sanfilippo and now powers popular systems such s Twitter, StackOverflow, GitHub, etc. Remote Dictionary Server or Redis for short is defined as a free, open-source in-memory database used as a cache or message broker. Let us start at the basics and discuss what is Redis and what is Memcached? What is Redis? In this article, we will break down the essential aspects of an in-memory database and compare them. They are both free, open-source in-memory databases that provide low latency for access to data.ĭespite these similarities, it can be quite a challenge choosing which to use for your applications. There are two competing options for in-memory key-value pair databases Redis and Memcached. ![]()
