MySQL 5.6 – InnoDB Memcached Plugin as a caching layer

March 29, 2013 By 10 Comments

MySQL 5.6 vs MySQL 5.5 and the Star Schema Benchmark

March 11, 2013 By 7 Comments

So far most of the benchmarks posted about MySQL 5.6 use the sysbench OLTP workload.  I wanted to test a set of queries which, unlike sysbench, utilize joins.  I also wanted an easily reproducible set of data which is more rich than the simple sysbench table.  The Star Schema Benchmark (SSB) seems ideal for this.

Introducing the pmp-check-mysql-status Nagios Plugin

March 29, 2012 By 2 Comments

Most of the Nagios plugins included with the Percona Monitoring Plugins are purpose-built for specific scenarios that I found in my research to be frequent, severe, or subtle causes of problems in MySQL systems. They are intentionally not generic because I wanted to focus on doing one thing with each plugin, and doing it excellently. [...]

Where does HandlerSocket really save you time?

March 16, 2011 By Leave a Comment

Somebody in the audience at Percona [...]

January 8, 2011 By 4 Comments

I am constantly referring to the amazing MySQL manual, especially the option and variable reference table. But just as frequently, I want to look up blog posts on variables, or look for content in the Percona documentation or forums. So I present to you what is now my newest Firefox toolbar bookmark: an option and [...]
