Peter Zaitsev at last year’s Percona University event in Montevideo
Later this week I’m excited to depart on a trip to South America. First I will stop in Montevideo, Uruguay, to meet with Percona’s team out there as well as to participate in our next Percona University event on April 29.
For those who do not know, Percona University events are free to attend and packed with technical presentations about MySQL and surrounding technologies, delivered by members of the Percona team and community speakers. Even though attendance is free, because space is limited you will need to …
[Read more]This blog post features a quick and interesting story from James (from ActionMessage), an early adopter of Sphinx. We met him at Percona Live: the MySQL User Conference, a few years back. This year, we asked if he would like to share his story with our community. Here it is. Enjoy! “I’m James Briggs from ActionMessage [...]
Three weeks ago I had the privilege of attending my first Percona Live MySQL conference, which was incredible! In particular, there were two things that I found impressive about the conference.
First, was the amount of knowledge sharing and support that MySQL users provide each other; it truly is a community. Coming from EMC, I’ve attended several conferences in the past, but I’ve always considered them more of a marketing focused event, mostly spent doing product launches and company roadmaps and not much time fostering knowledge sharing and informal get-togethers: Percona Live was different. There were well thought out tutorials, information packed presentations, and keynotes rife with practical knowledge culled from the real world. I had many great conversations at our booth with people that have evaluated TokuDB or TokuMX or were planning to as soon as they got back into the office. It was also great to see, and participate in, the …

If we want to run the application presented in "Writing a Fault-tolerant Database Application
using MySQL Fabric" with MySQL Fabric 1.4.2 Release
Candidate, some changes to the application are required. In
the previous post, we used MySQL Fabric 1.4.0 Alpha and many
changes have been made since this version. We can find an updated
version of the application here:
Recall that the application creates a simple database, a high availability group, registers the MySQL Servers into Fabric and runs a thread that mimics a client and another one that periodically executes a switch …

Apache Hadoop is commonly used for data analysis. It is fast for data loads and scalable. In a previous post I showed how to integrate MySQL with Hadoop. In this post I will show how to export a table from MySQL to Hadoop, load the data to Cloudera Impala (columnar format) and run a reporting on top of that. For the examples below I will use the “ontime flight performance” data from my previous post (Increasing MySQL performance with parallel query execution). I’ve used the Cloudera Manager v.4 to install Apache Hadoop and Impala. For this test …
