PC World has written a post with this title(*) about the upcoming MySQL Connect conference and references the Percona Live conference and an official Percona comment. As this is not syndicated in Planet MySQL I encourage you to read the full article.

The MySQL Connect Conference call for papers will open on April 16, 2012 for approximately three weeks.

I’m proud to announce the GA release of version 2.1 of Percona Toolkit. Percona Toolkit is the essential suite of administrative tools for MySQL.

Join Optimizations in MySQL 5.6 and MariaDB 5.5

This is the third blog post in the series of blog posts leading up to the talk comparing the optimizer enhancements in MySQL 5.6 and MariaDB 5.5. This blog post is targeted at the join related optimizations introduced in the optimizer. These optimizations are available in both MySQL 5.6 and MariaDB 5.5, and MariaDB 5.5 has introduced some additional optimizations which we will also look at, in this post.

Announcing Percona XtraBackup 2.0.0 GA

I’m really excited to today announce the first GA (Generally Available; i.e. stable) release of Percona XtraBackup 2.0. We have worked hard since our last major release on improving the reliability and user experience of Percona XtraBackup as well as adding features to make it better suited to more environments.

The 2.0.0 release contains no changes from the last beta (1.9.2), only the version number has changed.

New since 1.6:

Announcing Percona XtraBackup 1.6.6

I am happy to also announce the latest minor release in the Percona XtraBackup 1.6 series. We recognise that not everybody will want or be able to make the leap to our new major release, Percona XtraBackup 2.0 and so we’re also releasing Percona XtraBackup 1.6.6.

This is a minor release and source code and binaries can be downloaded from our downloads site. Our main APT and YUM repositories are now carrying Percona XtraBackup 2.0.0, so you won’t see 1.6.6 there.

Knowing when it’s lose-lose

I’ve been a consultant for over five years now and I’m just beginning to learn some basic things. One of them is how to spot a lose-lose customer relationship. I say I’m just beginning because I continue to find new lose-lose scenarios that I don’t see coming.
