pt-query-digest for MongoDB profiler logs

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.

5 years of MySQL

5 years of MySQL

People often write a blog post when they reach some nice anniversary since they joined MySQL community. Well, for those old enough it usually means when they joined MySQL AB as employee. For me this was January 2008. Because I didn't remember the month correctly, I haven't blogged anything then, but decided to save it for a better opportunity - now.

TL;DR Starting this week I will be working for 10gen, selling MongoDB to the Nordics. This blog post is really long - even then it doesn't contain the most interesting stories, I'm not sure if they can ever be published. Sorry for the length, but remember you don't need to read all at once. This is my last MySQL post so save some of it for cold winter days!

Showing my support

One of the greatest things with working in the MySQL community has been to meet so many people and travel in different countries and cultures. In my last blog post I mentioned how I learned that in Southern Europe it is considered offensive to go too early to meet your customer. As the customer is expecting you to come later than agreed (everyone always does), if you show up too early you are taking away time that he was expecting to still use to prepare for the meeting.

Slides from Failover or not Failover, that is the question

Below are the slides from my last talk at this Percona Live Worldwide MySQL Conference. The idea for this talk was proposed by my co-presenter Massimo Brignoli and goes back to a debate on this topic that went through the MySQL blogosphere during last Autumn - which in itself was sparked by an outstanding retrospective published about a MySQL failure at Github.

Slides from Spatial functions in MySQL 5.6, MariaDB 5.5, PostGIS 2.0 and others at Percona Live

Slides from my Percona Live talk evaluating the new spatial features in MySQL 5.6 and MariaDB 5.5 are now online. This is new material I have never presented before. It is based on work I have done in my job at Nokia HERE.com location services. So even if at this conference it draws less attention than my HA talks, it is actually what I'm most proud of to present.

TL;DR summary is that PostgreSQL has lots of features but MySQL has much better ease of use and performance. (I copy paste this standard sentence into any PostgreSQL vs MySQL evaluation I do :-) The MongoDB info is basically outdated, as the new 2.4 release introduces completely new implementation based on GeoJSON, new indexing, neither of which I tested.

There has been a public nomination period in January and the final voting is done by a panel who are themselves former winners of the award.
