The mysqlnd memcache plugin (mysqlnd_memcache) is an PHP extension for transparently
translating SQL into requests for the MySQL InnoDB Memcached Daemon Plugin (server plugin). It
includes experimental support for the MySQL Cluster Memcached Daemon. The server plugin provides
access to data stored inside MySQL InnoDB (respectively MySQL Cluster NDB) tables using the
Memcache protocol. This PHP extension, which supports all PHP MySQL extensions that use mysqlnd,
will identify tables exported in this way and will translate specific SELECT queries into Memcache
requests.

The MySQL native driver for PHP is a C library that ships together with PHP as of PHP 5.3.0. It serves
as a drop-in replacement for the MySQL Client Library (libmysqlclient). Using mysqlnd has several
advantages: no extra downloads are required because it's bundled with PHP, it's under the PHP
license, there is lower memory consumption in certain cases, and it contains new functionality such as
asynchronous queries.

NDB (MySQL Cluster) SQL tables through the Memcache protocol. This type of key-value access if
often faster than using SQL.
