Memcached plugin on MariaDB?
I'm wondering whether the memcached plugin has been added to MariaDB?
  


Not yet.  But slide 24 of mariadb-10-and-whats-new-with-the-project mentions:

 Plan is to have all important features of MySQL 5.6 by the time
 MariaDB 10.1.x is released as stable - For all practical purposes
 MariaDB 10.1.x will be a drop in replacement to MySQL 5.6"


https://kb.askmonty.org/en/what-is-mariadb-100/


New Features Backported from MySQL 5.6


New InnoDB — from MySQL 5.6.5



The thought being that the InnoDB Memcached Plugin would come along with InnoDB from 5.6.  Also see https://mariadb.com/blog/mariadb-10-vs-mysql-56-feature-comparison-update

https://jira.mariadb.org/browse/MDEV-4674 is a request for it
  https://github.com/MariaDB/server/pull/126 is a patch

The source is https://github.com/MariaDB/server , this is where it would be added.

Update, add link to related issue: https://jira.mariadb.org/browse/MDEV-12050 - "Remove unused InnoDB Memcached hooks from MariaDB Server"
