memcached 1.5.9 releases

Software

Memcached

Free & open source, high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

Memcached is an in-memory key-value store for small arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.

Memcached is simple yet powerful. Its simple design promotes quick deployment, ease of development, and solves many problems facing large data caches. Its API is available for most popular languages.

Memcached is a developer tool, not a “code accelerator”, nor is it database middleware. If you’re trying to set up an application you have downloaded or purchased to use Memcached, read your app’s documentation. This wiki and community will not be able to help you.

What is it Made Up Of?

  • Client software, which is given a list of available Memcached servers.
  • A client-based hashing algorithm, which chooses a server based on the “key”.
  • Server software, which stores values with their keys into an internal hash table.
  • LRU, which determine when to throw out old data (if out of memory), or reuse memory.
