A few interesting KPIs about certified people and their current location (the fact that many people travel from one country to the other for work is very popular these days especially in the IT sector): Before starting to read, I am hereby assuming the MySQL list of MCDBAs is on a residence basis not citizenship. There are [...]

In a Financial Times report today about RedHat's quarterly earnings, Sam Ramji of Microsoft takes note of MySQL and its influence as a key component in the general move towards open-source software:

Larger deployments of open-source to firms that already run the technology in a small way might be the most that happens, due to the fact that recessions make IT managers worry about risk. For the same reasons, a recession is not the time to switch a workforce to a new technology.

Microsoft is counting on that, while accepting that every leading company will soon be running at least some open-source software.

“It’s a heterogeneous world,” said Microsoft’s Sam Ramji. While Microsoft continues to warn about the legal and economic perils of relying on Linux and similar systems, Mr Ramji’s role is to make sure …

MySQL HA: 1. Desirable – most of the time, 2. Needed – often enough, 3. Available – there are some good options out there. Typical solutions consist of: Heartbeat with DRBD on Linux. Although HB was introduced to Linux, it can be used on Solaris, FreeBSD and others without the DRBD but with other solutions. Sun Cluster, Veritas (commercial), MySQL Proxy (still in [...]

While working with Monty Widenius on a bug I reported in MariaDB I was surprised to not get an IRC response for a few minutes. When committed Monty can identify, create a workaround, and patch a problem in code before you have time to read all the responses he also types. See my Monty’s Monument “Passion is a timeless wisdom” comment. One thing I forgot to say in that entry was, while 9pm in New york, it was at last 3am-5am Monty time.

We all love memorable quotes, so here is one.

“sorry, machine died; First time in years”

Introduction

If you, like me, are building or thinking of implementing a MySQL-powered application that has any need for prioritizing selecting certain data over other data, this article is for you.

Example

As a real world example, consider a queue-like video processing system. Your application receives new videos and processes them. The volume of incoming videos can at times be higher than the processing rate because the process is CPU bound, so occasionally a pretty long queue may form. You will try to process them as fast as you can but…

Note that I am using a queue here, so the the next item to be processed is a result of sorting by some sort of field in a ascending order, for example ORDER BY id or ORDER BY upload_date. Iâ€ll pick the id sort here.

…suddenly, you need to process a video somewhere in the middle of the queue or an important video enters and …

I didn’t announce it last week, but I did a MySQL University presentation on using MySQL with the ZFS filesystem. ZFS is the main filesystem for Solaris/OpenSolaris and offers a number of different benefits for people using MySQL, including some improvements to the ease of use, management, and performance of the storage you use with your MySQL database.

You can get the presentation, and the recordings of the presentation, from the appropriate MySQL University page: MySQL and ZFS.
