This release is the current GA (Generally Available) stable release in the 2.0 series.

Just in time for a PHP 5.5 code freeze, we are brushing over the Replication and Load Balancing plugin (PECL/mysqlnd_ms) and the Query Cache plugin (PECL/mysqlnd_qc) for PHP mysqlnd. PECL/mysqlnd_ms 1.5 is a step up from the previous version whereas PECL/mysqlnd_qc 1.1 is nothing but a maintenance release.

Replication and Load Balancing – better transaction awareness

PECL/mysqlnd_ms 1.5 monitors all mysqli function calls that change transaction status. Since PHP 5.5, te mysqli API gives you the same level of transaction control as SQL does. Thus, if only using mysql function calls, the plugin can do fully transaction aware load balancing.

We recently resumed our discussion around bringing Fractal Tree indexes to MongoDB.  This effort includes Tokutek’s interview with Jeff Kelly at Strata as well as my two recent tech blogs which describe the compression achieved on a generic MongoDB data set and performance improvements we measured using on our implementation of Sysbench for MongoDB.  I have a full line-up of benchmarks and blogs planned for the next few months, as our project continues.  Many of these will be deeply technical and written by the Tokutek developers.

We have a group …

Caution: This is just a fun post.

I was performing some testing on Windows the other day and encountered the following error in the error log:

130313  9:40:03 [ERROR] Error writing file 'G:\mysql\log.txt' (errno: 28)

Quickly, I ran “perror 28″ from the command line:

c:\>perror 28
Win32 error code 28: The printer is out of paper.

Hehe, really, Windows?!?

In fact, the drive was out of space. No more could be written to the general log, hence the error.

Fwiw, the Linux OS code 28 reports what you would expect:

OS error code  28:  No space left on device

So, if you ever run into “The printer is out of paper” error, you’ll know what to do.

Last night at the Golang-DC meetup I spoke about building (MySQL) database applications with Go. The meetup was well attended and people were very enthusiastic about Go. I spent a few minutes talking about Go in general, how VividCortex uses Go (we’ve built our agents, API servers, and all backend processes with Go), why we like it, some of the nice things it enables like making it easy to build very resilient programs, and then I gave the presentation, which I’ve embedded below.

Afterwards the discussion ranged to a lot of related topics. This was the best part of the evening for me. There were really great questions on a variety of topics, and insightful answers from everyone.

As we continue to see MySQL being implemented in bigger and more challenging environments, we are working to ensure Zmanda Recovery Manager for MySQL (ZRM) matches this growth and provides a comprehensive, scalable backup management solution for MySQL that can easily integrate into any network backup infrastructure.

The latest release of ZRM for MySQL is a significant next step, bringing disk space and network usage optimization and enhanced backup reporting, along with simplified management to help configure backups quickly and intelligently.   Additionally, ZRM for MySQL 3.5 now supports backup of MySQL Enterprise Edition, MySQL Community Edition, SkySQL, MariaDB, and MySQL databases running on latest versions of Red Hat Enterprise Linux, CentOS, Debian, Ubuntu and Windows – giving you an open choice for your MySQL infrastructure, now and in future, …

Percona CEO Peter Zaitsev leads a track at Percona MySQL University in Raleigh, N.C. on Jan. 29, 2013.

Percona MySQL University, Toronto is taking place this Friday and I’m very excited about this event because it is a special opportunity to fit a phenomenal number of specific and focused MySQL technical talks all into one day, for free.

Over the course of the day we will cover some of the hottest topics in the MySQL space. There will be talks covering topics like MySQL 5.6, MySQL in the Cloud and High Availability for MySQL, as well as Percona XtraDB Cluster for MySQL. We have talks planned for nearly every …

Here’s a solution to the not-so-long-standing issue of the Percona yum repo being broken for the CentOS 6 x86_64 version of the Percona-toolkit package. The repo listing is reporting an older version of the RPM which is not available on the site, so to fix this you just have to download the newer file and tell yum to add it locally. The side benefit is that you can use Yum to manage the RPM without adding the Percona repo, since the default settings for their repo could/have/had caused conflicts with Base Repo versions of MySQL packages; the Percona repo instructions set ‘enabled=1′ — not a great idea if you’re not setup to use the Yum priorities method of repo weighting.

So, if you see this after installing the repo via the instructions on their site:
