In preparing for this month’s Percona Live MySQL Conference and Expo, I’ve been reminiscing about the annual MySQL User Conference’s history – the 9 times it previously took place in its various reincarnations – and there are a lot of good things, fun things to remember.

2003 was the year that marked the first MySQL user conference independently organized by MySQL AB. It was called the “MySQL Users Conference” and took place at the Double Tree hotel near the San Jose airport with an estimated 500-600 people attending. Monty and David kicked-off the show with keynotes and I recall one of them saying something like, “12 …

Facebook is a major user of MySQL and has pushed the performance limits of the technology. Their MySQL experts have deep, hands on knowledge of the technology.

Catch the webinar: “Learn How MySQL 5.6 Makes Query Optimization Easier” for more tips on the 5.6 optimizer

While preparing the webinar I will deliver this Friday, I ran into a quite interesting (although not very impacting) optimizer issue: a “SELECT *” taking half the time to execute than the same “SELECT one_indexed_column” query in MySQL 5.6.10.

This turned into a really nice exercise for checking the performance and inner workings of one of the nicest features of the newer MySQL optimizer: the Index Condition Pushdown Optimization, or ICP, which …

As part of Percona Remote DBA for MySQL service we recognize that reliable backups are one of the most important things we can bring to the table. In my experience handling emergencies, the single worst thing that can happen is finding out you don’t have backups available when some sort of data loss or catastrophic event occurs.

With our Remote DBA service we can take care of backups for you, what follows are some of the internals of our implementation.

What kind of outages can happen?

• Someone runs UPDATE or DELETE and forgets the where clause or filters weren’t quite right
• The application had a bug causing data to be removed or overwritten
• A table (or entire schema) was dropped …

InnoDB Full-text Search in MySQL 5.6: Part 2, The Queries!

This is part 2 in a 3 part series. In part 1, we took a quick look at some initial configuration of InnoDB full-text search and discovered a little bit of quirky behavior; here, we are going to run some queries and compare the result sets. Our hope is that the one of two things will happen; either the results returned from a MyISAM FTS query will be exactly identical to the same query when performed against InnoDB data, OR that the results returned by InnoDB FTS will somehow be “better” (as much as it’s actually possible to do this in a single blog post) than what MyISAM gives us.

Recall that we have two different sets of …

MySQL 5.5 lock_wait_timeout: patience is a virtue, and a locked server

Like Ovais said in Implications of Metadata Locking Changes in MySQL 5.5, the hot topic these days is MySQL 5.6, but there was an important metadata locking change in MySQL 5.5.  As I began to dig into the Percona Toolkit bug he reported concerning this change apropos pt-online-schema-change, I discovered something about lock_wait_timeout …
