Memcached vs MySQL: What are the differences?
Developers describe Memcached as "High-performance, distributed memory object caching system". Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering. On the other hand, MySQL is detailed as "The world's most popular open source database". The MySQL software delivers a very fast, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server. MySQL Server is intended for mission-critical, heavy-load production systems as well as for embedding into mass-deployed software.
Memcached and MySQL can be primarily classified as "Databases" tools.
"Fast object cache", "High-performance" and "Stable" are the key factors why developers consider Memcached; whereas "Sql", "Free" and "Easy" are the primary reasons why MySQL is favored.
Memcached and MySQL are both open source tools. It seems that Memcached with 8.99K GitHub stars and 2.6K forks on GitHub has more adoption than MySQL with 3.97K GitHub stars and 1.56K GitHub forks.
Airbnb, Uber Technologies, and Netflix are some of the popular companies that use MySQL, whereas Memcached is used by Facebook, Instagram, and Dropbox. MySQL has a broader approval, being mentioned in 2991 company stacks & 3049 developers stacks; compared to Memcached, which is listed in 755 company stacks and 267 developer stacks.
