Codership, SkySQL und weitere Top-Experten rund um das Thema ‘MySQL Datenbanken” in Nürnberg versammelt
Unser Kollege Ralf Gebhardt ist dieses Jahr mit einem Vortrag zum Thema ‘Hochverfügbarkeitslösungen für die MySQL Datenbank’ auf der DOAG Konferenz zu hören und zu sehen. Weitere Interessante Themen sind z.B. ein Vortrag von Coderships Seppo Jaakola zu ‘Galera Cluster - synchronous multi-master replication for MySQL’.
Wir freuen uns auf Ihren Besuch beim MySQL-Stream der DOAG 2012 Konferenz!
Another Percona Live event is coming up, this time in London on the 3rd and 4th of December. I’m sure it is going to be as awesome as it was last year.
This year, I will talk about ‘Choosing Hardware For MySQL‘.
Of course, the most important hardware components will be
covered: CPU, Memory, Network, Disk Subsystem and also the
Cloud.
I will try to help attendees better understand how MySQL uses
hardware (and how it does not), how it optimizes random IO
operations on disk, what scalability means for MySQL, what it’s
limitations are and so on…
Want more? Just attend!

Percona Live London 2012 happens December 3-4 2012. Naturally Oracle has decided to back UKOUG in Birmingham with interesting talks as well, happening December 3-5 2012. This is akin to the recent San Francisco/New York split for MySQL Connect & Percona Live NYC 2012.
Lucky for us, Birmingham’s “MySQL day” seems to be December 5 2012, and by estimates, it takes about 1.5 hours for one to attend both events and see 3 days of MySQL related content.
That aside, I’m hoping this doesn’t happen in 2013. Splitting the community is never a good idea.

Palomino was honored to serve as part of the team of technologists on President Obama's re-election campaign. Atlantic Magazine ran a fascinating piece about Narwhal, the sophisticated data architecture that enabled the campaign to track voters, volunteers and online trends.
Palomino CEO Laine Campbell joined the team in Chicago for the final days of the campaign, ensuring maximum uptime and performance on the MySQL databases. Afterwards, President Obama thanked her for Palomino's contributions.

How To Install MySQL 5.6 On Ubuntu 12.10 (Including memcached Plugin)
According to What's New in MySQL 5.6, MySQL 5.6 will bring some performance improvements over MySQL 5.5. If you want to test out MySQL 5.6, you have to install one of the development releases from the MySQL downloads page because there is no stable release yet. This tutorial explains how to install the MySQL 5.6.8rc1 (Linux Generic) development release on an Ubuntu 12.10 server.
I have a soft spot for hierarchical databases. My first
database-related job was programming in M/Mumps. I know the
standard history of databases says that hierarchical databases
are a relic of the past, and that, thanks to Codd, relational
databases solve many of the problems of hierarchical (and other
kinds of) databases. I like relational databases – I was an
Oracle DBA, I’ve worked with DB2, Sybase, Postgres, mSQL, others,
and now MySQL. I really like InnoDB. However, I am
occasionally sad that hierachical databases seem a thing of the
past.
Or are they? Yesterday I had a thought that hierarchical
databases are much more widely used than relational
databases. In fact, maybe every single computer has a
hierarchical database that is used by every computer user,
whether they have database software installed or not. The
file system! Isn’t that a hierarchical database? The
idea …
I’m currently working on a new project about the explain
command output.
For my research I’ve read a lot of documentations, presentations
and blog posts and I would like to focus on the join type in
the explain output.
And in particular when type=index in
this explain output.
Take a look at what says the official documentation about type=index :
Wait a second, only the index tree is scanned? really?
This description seems to be the definition of a covering index.
But a covering index is only characterized by a
“Using index” in the extra column of the
explain output.
Consider the t1 table, just …
