ODTUG Kscope Wrap-up and Slides

Ronald Bradford and I produced a successful MySQL track at Kaleidoscope (hereinafter referred to as Kscope). With a speaker list of Philip Antoniades, Josh Sled and Craig Sylvester of Oracle, Laine Campbell of PalominoDB, Patrick Galbraith of Northscale, Sarah Novotny of Blue Gecko, Padrig O’Sullivan of Akiba, Dossy Shiobara of Panoptic.com and Matt Yonkovic of Percona, we knew the technical content was going to be great.

MySQL and Quoting

MySQL does not follow the ANSI SQL standard for quoting. MySQL’s default quoting behavior is that either single or double quotes can be used to quote a string (this gets me into trouble when I work with Oracle databases, as double quotes do not indicate a string!).

OpenSQLCamp Boston Pages are Online

OpenSQL Camp is a free unconference for people interested in open source databases (MySQL, SQLite, Postgres, Drizzle), including non-relational databases, database alternatives like NoSQL stores, and database tools such as Gearman. We are not focusing on any one project, and hope to see representatives from a variety of open source database projects attend.

Next Week’s MySQL Sessions at ODTUG Kaleidoscope

By now you know that there is a MySQL Track during next week’s ODTUG Kaleidoscope in Washington, DC. Ronald Bradford and I organized the schedule at the last minute (Ronald did a lot of the work!). It was difficult to fill a schedule with 19 sessions that are either 1 hour or 1.5 hours long, and to do it I ended up with three presentations. At each presentation I will be giving away a copy of The MySQL Administrator’s Bible, so be sure to show up! All MySQL track sessions are in Maryland C, and all times are Eastern.

The MySQL Track at Kaleidoscope is set!

A Useful Tool to Centrally Manage Many MySQL Instances

I have been talking with a group of folks who have been making a product that has lots of free functionality, including the ability to centrally manage many MySQL instances. The administration functions include starting and stopping MySQL, seeing status and system variables, seeing and managing the MySQL config file (/etc/my.cnf), seeing and managing accounts, a small dashboard of overall health graphs, and more.

An SSH tool to make your life easier

A user group member mentioned PuTTY Connection Manager. It wraps around PuTTY and gets the existing saved connections, makes a nicely tabbed browsing window where you can open sessions by double-clicking the connections, which are now listed on the right-hand side.

sort_buffer_size and Knowing Why

This article will explain why changing the sort_buffer_size kills performance and stability, it will also talk more about understanding why, an integral part against the “Battle against any guess.” Baron’s recommendation to leave sort_buffer_size as the default is just as bad as all the advice given to change the sort_buffer_size, because all that advice (including Baron’s) does not explain the underlying causes.

The Doom of XtraDB and Percona Server?

I have a hard time trying to figure out the deeper meaning behind Peter’s post, given that Percona writes a storage engine for MySQL, XtraDB. Does this mean that Percona will stop developing XtraDB? Does this mean that the Percona Server will diverge farther and farther away from MySQL so that they’re not compatible any more and migrating from MySQL to Percona Server is very difficult?
