MySQL 5.6 GA one year – What is next?
+3 Vote Up -0Vote Down

MySQL 5.6 has been GA for just over a year now. See MySQL 5.6.10 Release Notes.  Congratulations on your birthday! That is quite a long time. I was using it earlier in production because it worked and could do things that 5.5 could not do, but earlier versions were to use at your own risk, and indeed if prodded incorrectly would fall on the floor. That is fair enough because they were work in progress, yet if you poked them the right way they did a very good job.  Those dev versions have been long since upgraded which is good so they do not need quite as much care and attention.

So from where I see 5.6 it works very well. One big change that has made a large difference but which I think a lot of people may not really understand or use is the

Fun with Bugs #22 - Some Bug Reports You Should Not Miss
+0 Vote Up -0Vote Down
Yet another user installed MySQL 5.5.32 yesterday and got a system that can not start... It's really easy to help in this case - just downgrade back to 5.5.31 or upgrade to 5.5.33 if you can. Why problem happened during upgrade? Because of a regression bug #69623.

This case that was easily solved during a quick chat reminded me about the problem of bugs in production. Nobody expects any sane DBA to review every new bug report, but some of them should not be missed, at least when upgrading to any newer version. Regression bugs (I see 15

MySQL 5.5's new features
+0 Vote Up -0Vote Down
The recently released MySQL 5.6 gets a lot of attention, but for those who are still on 5.5 there is also good news: There are two new features in 5.5.

The first feature is that there are more INFORMATION_SCHEMA tables for InnoDB. This means that it's possible to 'see' what's in the buffer pool. It also makes it possible to get more information about the LRU list.

From the 5.5.28 changelog:
InnoDB: Certain information_schema tables originally introduced in MySQL 5.6 are now also available in MySQL 5.5 and MySQL 5.1: INNODB_BUFFER_PAGE, INNODB_BUFFER_PAGE_LRU, and INNODB_BUFFER_POOL_STATS. (Bug #13113026)

This is in the "Bugs Fixed" section instead of the "Functionality Added or Changed" section, which is a bit weird in my opinion.

The second feature is a

Tungsten Replicator 2.0.7 is released
+5 Vote Up -0Vote Down

Tungsten Replicator 2.0.7 was released today. In addition to a large number of bug fixes, this release adds several improvements for multi-master management, and support for Amazon RDS (as a slave).

While the Release Notes show a long list of improvements, I would like to focus on some of them that improve the handling of multi-master deployments.

When we released version 2.0.6, we added the first revision of the cookbook recipes in the build. That was still a green addition, which caused several bug reports. But since then, we have integrated the cookbook in our internal testing, making these recipes more robust and reliable. We are also planning to improve

MySQL Sandbox 3.0.30 - now adapted to work with 5.5.30 and 5.6.10
+6 Vote Up -0Vote Down

The latest releases of MySQL Sandbox, in addition to deal with minor bugs, have mostly been necessary because of compatibility issues in MySQL, both 5.5 and 5.6.

When I found that MySQL 5.6 has some InnoDB tables inside the 'mysql' schema, I had to change the way that the sandbox used to remove all contents (the ./clear command.)

To achieve a smooth clean up, MySQL Sandbox now performs a dump of the mysql schema, and uses that saved data to restore the schema after a complete wipeout.

Unfortunately, when 5.5.30 was released, this operation resulted in a warning, due to a behavioral change.

After a careful change, and about 1200 unit tests, the latest version of MySQL Sandbox should work well with every MySQL release from 5.0 to 5.6.

Do we need a MySQL Cookbook?
+2 Vote Up -2Vote Down

The blog title says it all: Do we need a MySQL Cookbook? I tend to think so.

This seems to be something that is missing with current MySQL documentation. There is lots of information available but finding the appropriate bit can be quite tedious and it often requires looking in multiple places.

A lot of other software has such books, but for some reason MySQL seems to be missing one.

A recent example comes from a “documentation feature request” I posted today: http://bugs.mysql.com/bug.php?id=68171. MySQL 5.6 provides a way to “move InnoDB tables” from one server to another. There are many reasons why you may want to do it, but the documentation is currently rather sparse. A simple “example recipe” for this would be good, as would an equivalent recipe for other

On Friday last week, after the intensive days of the conference, Ars Technica wrote and published a nice article about MariaDB including many of the messages we had been delivering during the conference, http://arstechnica.com/business/news/2012/04/mysql-founders-latest-mariadb-release-takes-enterprise-features-open-source.ars.

Some lessons from MySQL Conference 2012
+9 Vote Up -0Vote Down

The Percona Live MySQL Conference and Expo 2012 is over. Together with the SkySQL solutions day, it has kept me occupied for 4 full days, from early morning to late at night.

I have to say that I am pleased. The quality of the organization was very high, with a very good lineup of speakers and an excellent technical support.

As usual, I have learned a lot during this week, either directly, by attending talks, or indirectly, by meeting people who told me what was juicy at the talks that I had missed. And I have met new interesting people, and caught up with the people that I know already.

This conference was particularly intense also because I got myself involved in 5 talks, which was probably more than I should have. How did
