memcached vs redis

Redis vs Memcached vs MongoDB. Both Redis and Memcached have many open-source clients available for developers. Memcached vs Redis: Direct Comparison Both tools are powerful, fast, in-memory data stores that are useful as a cache. Applications can use these more advanced data structures to support a variety of use cases. Often, we think about caching to improve performance while processing a large amount of data. Memcached supports keys with a maximum size of 250B and values up to 1MB. Amazon ElastiCache supports the Redis and Memcached cache engines. Since Redis is predominantly single-threaded and has native support for clustering, it grows well horizontally. With both ElastiCache for Redis and ElastiCache for Memcached you: Additonally, ElastiCache for Redis features an enhanced engine which improves on the reliability and efficiency of open source Redis while remaining Redis-compatible so your existing Redis applications work seamlessly without changes. However, it can grow much larger than an RDB snapshot. 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. However, based on our experience, it's important to consider its pros and cons right from the beginning to avoid changes and migrations during the project. 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. Redis uses an encapsulated version of the malloc/free memory management, being a simpler approach compared to the Memcached Slab mechanism, as I'm going to explain below. Redis is more powerful, more popular, and better supported than memcached. While Redis is an in-memory (mostly) data store and it is not volatile, Memcached is an in-memory cache and it is volatile. Redis vs Memcached: Which One to Pick. Redis is single-threaded and will beat Memcached on small data reading and writing. Unlike Redis, Memcached has no data types, as it stores strings indexed by a string key. It provides two major persistence policies, RDB snapshot and AOF log.

Redis is surely more flexible and powerful, but Memcached does serve some purposes very well and in some cases achieves better performance. 1. Memcached: Redis; DB-Engines blog posts: Redis extends the lead in the DB-Engines key-value store ranking 3 February 2014, Matthias Gelbmann. Memcached can only do a small fraction of the things Redis can do. Any Redis data type command would have been translated to many commands, along with some data processing in between them to achieve the same result. Memcached has a higher rate of memory use for easy storing of key values. Concerning the migration, it was very easy to perform as Redis supports most of the commands that Memcached does. Redis is an open source, in-memory data structure store, used as a database, cache and message broker. By being multi-threaded it has advantages, especially when working with big data.

Although they are both easy to use and offer high performance, there are important differences to consider when choosing an engine. Redis has purpose-built commands for working with real-time geospatial data at scale. This file is also stored in disk, so by re-running all the commands in their order, a dataset can be restored on startup. Memcached is volatile store and Redis is non-volatile. The AOF log is better if data loss is not acceptable at all, as it can be updated at every command. It leads to efficiency, once it requires less I/O operations. Memcached has better performance for big data, such as data of 100k or above. At Imaginary Cloud we have used both in many different client’s projects.
