I recently gave a presentation at Percona Live 2015 in Santa Clara, CA. In this presentaiton I originally wanted to simply show running MySQL replication, first asynchronous, and more importantly, a Galera cluster, and in so doing, demonstrate how useful Kubernetes is.

Why?

The talk was a good chance to introduce the MySQL community– developers, DBAs, sysadmins, and others to what Kubernetes is and what it means for MySQL

A bit of learning

I thought at the time when I submitted my synopsis that the talk would be straightforward. About 2-3 months ago, I started working on the setup I would use for the demonstration. My goal was to use a stock CoreOS cluster with the necessary Kubernetes components installed and running as a cluster.

The …

What?

MySQL 5.7 server binaries compiled with the OpenSSL library now make it easy to set up SSL/TLS and RSA artifacts, and to enable them within MySQL. Two new read-only global options have been introduced through this work:

• --auto-generate-certs: Enables automatic generation and detection of SSL artifacts at server start-up.
• --sha256-password-auto-generate-rsa-keys: Enables automatic generation of an RSA key pair.

These options govern automatic generation and detection of SSL/TLS artifacts and RSA key pairs respectively. Auto generated files are placed inside the data directory, and both options now default to ON.

For the …

In a previous post, we gave you a quick overview of the MaxScale load balancer and walked through installation and configuration. We did some quick benchmarks using sysbench, a system performance benchmark that supports testing CPU, memory, IO, mutex and also MySQL performance. We will be sharing the results in this blog post.

Sysbench setup

For our tests we used the latest version of sysbench, straight from bzr. Installation is simple. First, make sure you have all the prerequisites. For Ubuntu these are: libmysqlclient-dev (or equivalent), bzr, automake, make, libtool and libssl-dev.

Get the code and compile it:

$ cd /root
$ bzr branch lp:sysbench
$ cd /root/sysbench
$ …

Last week at Percona Live, VividCortex received the MySQL community award for 2015 Application of the Year.

Baron Schwartz, our founder and CEO, is quoted, “It’s an honor to receive this award from the MySQL community. We aim to raise the bar for database monitoring the same way MySQL has raised the bar for open source databases. Our product would not be at this point without the dedication and help of our employees, friends, customers and investors. We thank them for their support and look forward to many years of mutually beneficial relationships. On a personal note, as a previous recipient of Community Member of the Year award, and having dedicated the last decade of my life to the MySQL community, this is deeply meaningful to me.”

So I am now back in my office in Vancouver, BC after an amazing week in Santa Clara for the Percona Live MySQL Conference and Expo. I though that I would take a break from trying to catch up with my email and write down some quick thoughts about this great event. 

This year's event was announced to be the largest in several years, with an estimated 1200 people in attendance. To me what stands out about this number is just how it supports the fact that the MariaDB and MySQL community is growing and stronger than ever. If we assume that each of the 1200 attendees were our of the office for the full three days we are looking at 28,800 hours dedicated to learning and sharing about MariaDB and MySQL at this event!

This year our team has eight talks/tutorials and keynotes combined. You can see a full list of our …

Somebody suggested that I try out thin, “A fast and very simple Ruby web server.” So, I thought it might be interesting to test, and a simplification over Rails to demonstrate an small Ruby MVC pattern.

Installing thin seemed straight forward as a gem installation, like

gem install thin

The initial install didn’t work out of the box because I’d neglected to install the gcc-c++ library. It raised the following errors:

Fetching: eventmachine-1.0.7.gem (100%)
Building native extensions.  This could take a while...
ERROR:  Error installing thin:

You can send binlog events in realtime from the binary logs with FlexCDC to Kafka (or any system) to take advantage of both worlds.
