I’m pleased to announce that Oracle is sending some of their top technical people to speak at the Percona Live MySQL Conference and Expo. The conference takes place April 22-25, 2013 at the Santa Clara Convention Center and Hyatt Santa Clara.

Tomas Ulin, VP, MySQL Engineering for Oracle, will present an invited keynote talk on “Driving MySQL Innovation” during the Tuesday morning opening keynotes. With the recent release of MySQL 5.6, conference attendees will hear about the latest developments of this major MySQL release.

In addition to Tomas, Oracle MySQL technologists will also lead three breakout …

Taxonomy upgrade extras: galeramyisaminnodbstorage engine

Switching from MySQL/MyISAM to Galera Cluster requires that all tables (except those from the mysql, information_schema and performance_schema) are using the InnoDB Storage Engine.

For altering the Storage Engine of the tables we wrote a script (alter_engine.pl) long time ago already. Because we have made many of those switches recently we have extended its functionality.

Heyo!

March 13th at 12:00pm PDT (19:00 GMT) is the time to check in and hop online for #DBHangOps this week. Keep an ever watchful eye on the twitter search and hop on the google hangout to contribute some discussion! This week's topics are:

• Monitoring
  • What do you consider to be "standard" nagios checks for MySQL
• Demos of Anemometer and MySQL Enterprise Monitor
• Daily pain MySQL Bugs and Gotchas (e.g. show table status being cached)
• MySQL 5.6

See all of ya on the google hangout! :)

One of the most rewarding things you can do is help someone get a great job or hire a great person for the position they need to fill. I have traveled a lot, written books, done a bunch of consulting, and spoken widely on MySQL, other databases, open source, and so forth. I’ve gotten to know a lot of people, some I’d call good friends, and many of them are leading large organizations.

I was a guest on the Food Fight Show last week, along with a bevy of really smart people asking and answering tough questions on fault detection. We didn’t talk a lot about MySQL, but given that VividCortex is focusing on MySQL initially, pretty much all of my experience with zero-threshold, zero-configuration fault detection is MySQL-based. It’s a fun conversation with a lot of insights into the industry, what’s wrong with current monitoring tools, and where monitoring is going.

What this is about

The following is a review of the real status about Amazon RDS in comparison with EC2.

The purpose is to have a better understanding of possible limitation in the platform usage, and what is a possible fit and what not.

Why

I did a first review an year ago for internal purpose, but now we are receiving the same questions over and over from different customers.

Given that and given a lot of things could happen in one year, I have decide to repeat the review and perform the tests once again.

What needs to be underline is that, I am doing this in consideration of a usage in PRODUCION, not as QA or development.

So my considerations are obviously focus on more demanding scenarios.

There are many thing changed in MySQL 5.6 which are related to passwords:

• There is a new password hash algorithm (SHA-256)
• There is obfuscation for passwords with the .mylogin.cnf file.
• The option to store slave passwords in a database table.
• It's now possible to supply a password to START SLAVE.

But that's not what this blog post is about.

This blog post is a great new feature: Hiding passwords from your log files, automatically.

MySQL 5.6 will by default hide passwords from the general log. This is not just obfuscation as only the one-way hash will be put in the log files. By setting log-raw=OFF you can disable password hiding for the general log. The log-raw setting will only influence the general log, so the passwords in the slow query log and the binary logs will still be hidden.

With MySQL 5.5 this could be done manually by …

I’m going to take the numbers from my previous post, MySQL Modularity, Are We There Yet? for the “kernel” size of MySQL – that is, everything that isn’t a plugin or storage engine.

For Linux kernel, I’m just going to use the a-bit-old git tree I have on my laptop. I’ve decided that the following directories are for “plugins” drivers/ arch/ sound/ firmware/ crypto/ usr/ virt/ tools/ scripts/ fs/*/* and everything else is core kernel code.

During the second half of our CUBE discussion with Wikibon analyst Jeff Kelly at this year’s Strata Conference in Santa Clara, we talked about the tipping point for Big Data. Strata veterans could see at a glance that this year’s conference was markedly different. No longer the exclusive domain of geeks and database administrators, this year’s Strata featured some of the biggest enterprise vendors around. With heavy weight enterprise players Intel and EMC Greenplum announcing their own Hadoop distributions, big data is clearly going mainstream. Now that we know how to capture, store, access and analyze big data, what’s the next step? Listen in to hear my conversation with Jeff Kelly about taking big data down its last mile and finally putting it in the hands of business users.
