So, what is HandlerSocket? Adam Donnison wrote a great blog on how to get started with it, but if you are developing MariaDB applications using C, C++, PHP or Java what good does HandlerSocket do you?

HandlerSocket in itself is a MariaDB plugin, of a type that is not that common as is is a daemon plugin. Adam shows in his blog how to enable it and install it, so I will not cover that here. Instead I will describe what it does, and doesn't do.

Installing HandlerSocket on RHEL 6 + Percona-Server 5.5 in Five(ish) Easy Steps

As a followup to my previous post on installing HandlerSocket on CentOS 5 + Percona-Server 5.1, I’ve been asked to provide an updated HOWTO for RHEL 6 + Percona-Server 5.5.
