I have a bunch of notes from the O’Reilly MySQL Conference & Expo 2011, and I figure its about time I started blogging it. These are notes from the panel on the SkySQL Reference Architecture, led by Kaj Arno and Ivan Zoratti. The notes are raw (read their FAQ for more), and I talk a little bit about the SkySQL Configurator at the end (a tool I immediately used, and submitted some bugs/improvements for – 7 at last count, which I hear got fixed in the 0.02 release, which got pushed last night!).

There were 7 panelists. The MySQL world needs:

• technical support
• monitoring & administration

MariaDB 5.1 was released in February 2010. MariaDB 5.2 was released in November 2010. In terms of download numbers of MariaDB binaries from mariadb.org, we’ve seen 4x growth, and this is always good news (yes, we had our best download month in November 2010).

I run MariaDB on about six production servers of mine. All the Monty Program infrastructure that uses a database runs MariaDB (varying from 5.1 and 5.2). Monty Program have customers that are using MariaDB in production, and for that, watch out for some case studies.

Now I’d like to know: are you running MariaDB in a production environment?

Does it power your blog? Does it power a huge number of your servers? Have you migrated from another database? I’d like to know. Please shoot colin[AT]montyprogram[dot]com an email so I get a better feeling of how

Lately, I've had a few people ask me "How much data is in our database?". Sure, you can look at the file sizes of MyISAM tables and indexes and get a ballpark figure, but what if you need exact results, or are running InnoDB storage engine? That proves to be more challenging! In playing around with the information_schema, I've put together some queries to help:

Calculate Index Sizes

mysql> SELECT CONCAT(ROUND(SUM(index_length)/(1024*1024*1024), 2), ' GB') AS 'Total Index Size'
FROM information_schema.TABLES 
WHERE table_schema LIKE 'database'; 

+------------------+
|Total Index Size  |
+------------------+
|1.70 GB           |
+------------------+

1 row in set (1.60 sec) 

Calculate the Total Size of Stored Data

mysql> SELECT CONCAT(ROUND(SUM(data_length)/(1024*1024*1024), 2), ' GB') AS

On the front cover of MySQL Administrator’s Bible is a sentence that reads:

“The book you need to succeed!”

I must say, I do agree. Authored by two very experienced DBAs, Sheeri Cabral and Keith Murphy,
they’ve combined their talents to cover what you really need to know to
succeed. This book is very versatile. If you’re new to MySQL, or
experienced in another database and have to start administrating MySQL,
you need this book. I can honestly say, even if you have years of MySQL
experience, you will learn

What do you do when you're in a situation where you REALLY need your
favorite Maatkit tools, but are not allowed to load software on the
server running MySQL, AND you're not allowed to install software on the
provided workstation, especially a workstation that's running software
from a large corporation in Redmond? Portable Maatkit to the rescue!

DISCLAIMER:
I've only tested a few maatkit tools, namely mk-find and
mk-query-digest, but not completely. Some features and some tools may
not function, such as mk-audit. Use your best judgment. I'm not
responsible if your workstation or server looses all your data, your
USB key bursts into flames, or your significant other leaves you. YMMV,
use at YOUR OWN RISK!

First up: I normally read Planet MySQL from an RSS reader. I am assuming you do too. But in the interest of all the new features that the website itself has, I thought I’d take some time to talk about them in brief (to respect your time). Needless to say, go forth and check out Planet MySQL if you’ve not been there in a while.

A change in URL

We used to go to http://planetmysql.org but now it redirects to http://planet.mysql.com/.

Its also worth noting that from a Google PageRank of 8, Planet MySQL has dropped to a PageRank of 6. One wonders why?
