November 4, 2013 By Severalnines Percona Live London MySQL Conference - 11-12th November, 2013

We’re particularly excited about this year’s Percona Live London MySQL Conference. The line-up of speakers & topics looks excellent and it’s good to see speakers from Oracle, Percona, the MariaDB Foundation (amongst others) scheduled at the same event. It demonstrates not just the diversity of the ever broadening MySQL ecosystem, but also the fact that there really is room for everyone to contribute, participate in and advance MySQL in manifold directions while still retaining a …

Percona XtraDB Cluster – A Drop-in-place Clustering Solution for MySQL
+0 Vote Up -0Vote Down

Emphasis on clustering solutions comes up quite a lot when talking to customers about High Availability. The reason is because clustering is supposed to provide an easier solution for maintaining high availability and so that you do not have to rely on other tools and techniques outside of the database server. I thought it would be good to share the gist of many of my discussions around clustering, in the form of a blog post. So here I will be doing a high-level comparison between MySQL NDB Cluster and Percona XtraDB Cluster.

The post …

Hong Kong (OpenStack Summit)
+0 Vote Up -0Vote Down

I’ll be in Hong Kong for the upcoming OpenStack Summit Nov 5-8. I’d be thrilled to talk database things with others present, especially around Trove DBaaS (DataBase as a Service) and high availability MySQL for OpenStack deployments.

I was last in Hong Kong in 2010 when I worked for Rackspace. The closest office to me was in Hong Kong so that’s where I did my HR onboarding training. I remember telling friends on the Sunday night before leaving for Hong Kong that I may be able to make dinner later in the …

It’s getting close to time to head to Auckland for OSDC and a few days ago I blogged about how I’m speaking there). I’ll be speaking on MySQL In the Cloud, As A Service and all of the challenges that can entail as well as on The Agony and Ecstasy of Continuous Integration. Both of these talks draw heavily on the experience of …

The end of Bazaar
+2 Vote Up -0Vote Down

I’ve used the Bazaar (bzr) version control system since roughly 2005. The focus on usability was fantastic and the team at Canonical managed to get the entire MySQL BitKeeper history into Bazaar – facilitating the switch from BitKeeper to Bazaar.

There were some things that weren’t so great. Early on when we were looking at Bazaar for MySQL it was certainly not the fastest thing when it came to dealing with a repository as large as MySQL. Doing an initial branch over the internet was painful and a much worse …

Forking MySQL/ for how long can forks keep up?
+13 Vote Up -3Vote Down
  • Fact: MySQL 5.6 was released as GA in February 2013
  • Fact: MySQL 5.6 has been available with its complete set of features since September 2012
  • Fact: On September 21st, Oracle has released MySQL 5.7.2, which is the de facto major release after MySQL 5.6 (5.7.1 was just a token “we’re-still-in-business” release).
  • Fact: As of today, there is no GA-ready fork of MySQL 5.6.

Percona Server is still in RC state, while MariaDB, with its runaway version 10, is still in alpha state. Of …

Are MariaDB tests adding anything extra over Oracle MySQL tests?
+3 Vote Up -0Vote Down

I grabbed all the tests introduced in MariaDB 5.5.32 (i.e. “bzr diff -rtag:mariadb-5.5.31..mariadb-5.5.32 mysql-test/” and some foo) and threw them in their own test file. I only kept tests for crashing bugs and ignored those that required plugins (there were two or three, but nothing major). So now I have a test file that should crash MariaDB 5.5.31 and probably before. But, the question is: does this crash Percona Server or MySQL?

While it is excellent to see the MariaDB guys including tests for …

pt-query-digest for MongoDB profiler logs
+2 Vote Up -0Vote Down

One of my favorite MySQL tools ever is pt-query-digest. It's the tool you use to generate a report of your slow query log (or some other supported sources), and is similar to for example the Query Analyzer in MySQL Enterprise Monitor. Especially in the kind of job I am, where I often just land out of nowhere on a server at the customer site, and need to quickly get an overview of what is going on, this tool is always the first one I run. I will show some examples below.
