Memcached is free and open source caching solution. It is distributed caching that enables a large amount of data to be cached.
Memcached has been used in thousands of web applications for improving performance. Since IO based applications are slower, Memcached can add a lot of improvement in performance by caching it and serving all data from RAM.
Memcached is a key-value store, that requires a key to be unique across the whole cache. This requires a lot of thinking before implementing the solution in an existing application.
Though its is very popular, I did not find many good books talking in depth about Memcached. Below compilation is an effort to bring all the good books at one place. If you know of a better book, please share it in the comments section.
