In The Doom of Multiple Storage Engines, Peter talks about how the storage engine concept of MySQL is usually spoken of in positive terms, but there are many negatives.

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?

Or maybe it’s just that Peter is saying one thing and doing the opposite; which just seems wrong because that would be blatant hypocrisy on Percona’s part.

(This idea was a comment on the blog post but seems to be trapped in the spam filter, so I’m …

[author's note: personally, I use awk a bunch in MySQL DBA work, for tasks like scrubbing data from a production export for use in qa/dev, but usually have to resort to Perl for really complex stuff, but now I know how to do .]

Basics:
By default, fields are separated by any number of spaces. The -F option to awk changes the separator on commandline.
Print the first field, fields are separated by a colon.
awk -F: '{print $1}' /etc/passwd

Print the first and fifth field:
awk -F: '{$print $1,$5}' /etc/passwd

Can pattern match and use files, so you can replace:
grep foo /etc/passwd | awk -F: '{print $1,$5}'
with:
awk -F: '/foo/ {print $1,$5}' /etc/passwd

NF = built in variable (no $) used to mean “field number”
This will print the first and last fields of lines where the first …

The Beacon Pattern:
- This is a “Get out of the business” pattern
- Identify an oft-occurring and annoying task
- Automate and document it to the point of being able to hand it off to someone far less technical

Example:
- System admins were being put in charge of scheduling rooms in the building
- They wrote a PHP web application to help them automate the task
- They refined the app, documented how to use it, and handed it off to a secretary
- They have to maintain the app, but it’s far less work.

The Community Pattern:

- Prior to launch of a new service, create user documentation for it.
- Point a few early adopters at the documentation and see if they can use the service with minimal support
- Use feedback to improve documentation, and the service
- Upon launch, create a mailing list, forum, IRC channel, or Jabber chat room and ask early …

I am attending the Professional IT Community Conference – it is put on by the League of Professional System Administrators (LOPSA), and is a 2-day community conference. There are technical and “soft” topics — the audience is system administrators. While technical topics such as Essential IPv6 for Linux Administrators are not essential for my job, many of the “soft” topics are directly applicable and relevant to DBAs too. (I am speaking on How to Stop Hating MySQL tomorrow.)

So I am in Seeking Senior and Beyond: The Tech Skills That Get You Promoted. The first part talks about the definition of what it …

On Monday, Ronald Bradford posted that the independent Oracle Developer Tools User Group had opened up their Kaleidoscope Conference, well-known throughout the Oracle community for in-depth technical sessions for developers, to the MySQL community. Giuseppe Maxia posted his thoughts on Tuesday.

We have confirmed that there will be an entire MySQL track at Kaleidoscope! Because Kaleidoscope is less than 8 weeks away, we could not go through a standard call for papers. Ronald and I have been working to come up with appropriate topics and speakers for an audience that uses MySQL but is probably more familiar with Oracle. We contacted folks we thought …

Here’s a matrix of all the videos up on YouTube for the 2010 O’Reilly MySQL Conference and Expo. The matrix includes the title, presenter, slide link (if it exists), video link, and link to the official conference detail page, where you can rate the session and provide feedback that the presenter will see. They are grouped mostly by topic, except for the main stage events (keynote, ignite) and interviews.

If there’s a detail missing (ie, slides, or there are other videos you know about), please add a comment so I can make this a complete matrix.

Here’s a sneak peek at a video matrix — this is all the videos that include Pythian Group employees at the MySQL conference. I hope to have all the rest of the videos processed and uploaded within 24 hours, with a matrix similar to the one below (but of course with many more sessions).

This is not my notes about the MySQL conference that just occurred. These are my thoughts about MySQL conferences in general. Baron wrote in The History of OpenSQL Camp:

After O’Reilly/MySQL co-hosted MySQL Conference and Expo (a large commercial event) that year, there was a bit of dissatisfaction amongst a few people about the increasingly commercial and marketing-oriented nature of that conference. Some people refused to call the conference by its new name (Conference and Expo) and wanted to put pressure on MySQL to keep it a MySQL User’s Conference.

During this year’s conference, I heard a lot of concern about whether or not O’Reilly would have a MySQL conference, and whether or not Oracle would decide to sponsor. I heard all of the following (in no particular order):

* If O’Reilly does not have a …

Chief Corporate Architect at Oracle, been at Oracle since 1986, technology and architecture decisions, responsible for all open source at Oracle. Company-wide initiatives on standards management and security — http://en.oreilly.com/mysql2010/public/schedule/detail/12440.

Where MySQL fits within Oracle’s structure.

Oracle’s Strategy: Complete. Open. Integrated. (compare with MySQL’s strategy: Fast, Reliable, Easy to Use).

Most of the $$ spent by companies is not on software, but on integration. So Oracle makes software based on open standards that integrates well.

Most of the components talk to each other through open standards, so that customers can use other products, and standardize on the technology, which makes it much more likely that customers will continue to use Oracle.

Oracle invested …

I’m excited to share the news that Oracle ACE program has been extended to cover MySQL community now and Pythian’s Sheeri Cabral has become the very first Oracle ACE Director in MySQL expertize area. It’s a special privilege for me to blog about it because I had a pleasure to nominate Sheeri in the first place. Being an Oracle ACE Director myself and knowing what’s involved, I believed that if Oracle ACE program is extended to MySQL, Sheeri must be the number one candidate.

It’s impossible to overestimate Sheeri’s role in the MySQL community — her advocacy for the technology and commitment to building and supporting the community. She’s been presenting about MySQL …
