Hello all,

I hope you're doing well. After the successful event last year it's a no brainer to arrange another community dinner when we're all together again in London this November. We had a fantastic turn-out for the meal last year, seating over 100 MySQLers in a venue whom were expecting only 60. So this year join the MySQL community again for a bite to eat and a beverage or two and discuss life, love and data.

The Why
We have a vibrant community surrounding the MySQL ecosystem. Whether you want to talk about the meaning of life with Colin Charles or find out how Facebook take their logical backups even quiz Shlomi Noach about where thinks up his latest and greatest MySQL tools; why not do it with a curry and a …

During April’s Percona Live MySQL Conference and Expo 2014, I attended a talk on MySQL 5.7 performance an scalability given by Dimitri Kravtchuk, the Oracle MySQL benchmark specialist. He mentioned at some point that the InnoDB double write buffer was a real performance killer. For the ones that don’t know what the innodb double write buffer is, it is a disk buffer were pages are written before being written to the actual data file. Upon restart, pages in the double write buffer are rewritten to their data files if complete. This is to avoid data file corruption with half written pages. I knew it has an impact on performance, on ZFS since it is transactional I always disable it, but I never realized how important the performance impact could be. Back from PLMCE, a friend had dropped home a Dell R320 server, asking …

I started using MySQL 11 years ago.  That’s not too long compared to other people in the industry, but nonetheless here’s my perspective on the state of the MySQL industry after attending Percona Live MySQL Conference & Expo 2104.

In short, the attitude around MySQL has changed from “Does it work?” to “Is it fast and reliable?” to “How do we manage it?” To further generalize, these periods correspond roughly to the original MySQL AB team, Percona and Oracle, and the last period is the current period so key players are emerging, like WebScaleSQL.

Does it work?

Peter Zaitsev said in one of his keynote talks that MySQL used to be considered a toy.  Today …

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 …

210 people registered for the inaugural “Open Source Appreciation Day” March 31 in Santa Clara, Calif. The event will be held each year at Percona Live henceforth.

To kick off the Percona Live MySQL Conference & Expo 2014, Percona held the first “Open Source Appreciation Day” on Monday, March 31st. Over 210 people registered and the day’s two free events focused on CentOS and OpenStack.

The OpenStack Today event brought together members of the …

The MySQL community continues to amaze me, everyone is friendly and always willing to answer questions and help others. It’s always nice to meet people in-person that I’ve met virtually in the last 12 months. Percona Live 2014 MySQL Conference and Expo in Santa Clara just wrapped up and I wanted to share my highlights of the event before I unplug for the weekend.

• I heard several stories of people’s experiences with TokuDB, open sourcing 12 months ago has been a huge success for Tokutek. We have a growing community in our tokudb-user Google Group, please share your experiences and help others.
• In his “Galera Cluster New Features” presentation, Sappo Jaakola of …

Facebook’s Yoshinori Matsunobu

I spoke with Facebook database engineer Yoshinori Matsunobu here at Percona Live 2014 today about a range of topics, including MySQL at Facebook, the company’s recent move to WebScaleSQL, new MySQL flash storage technologies – and why attending the Percona Live MySQL Conference and Expo each year is very important to him.

Facebook engineers are hosting several sessions at this year’s conference and all have been standing room only. That’s not too surprising considering that Facebook, the undisputed king of online social networks, has 1.23 billion monthly active …

ScaleArc recently hired Percona to perform various tests on its database traffic management product. This post is the outcome of the benchmarks carried out by Uday Sawant (ScaleArc) and myself. You can also download the report directly as a PDF here.

The goal of these benchmarks is to identify the potential overhead of the ScaleArc software itself and the potential benefits of caching. The benchmarks were carried out with the trunk version of sysbench. For this reason, we used a very small set of data, so the measurements will be fast, and it’s known that caching has huge benefits when the queries themselves are rather expensive. We decided that we would rather show that benefit with a real-world application, which is coming later is this series. And if you’re in the Silicon Valley area, be sure to join us this evening at the …

Facebook, the undisputed king of online social networks, has 1.23 billion monthly active users collectively contributing to an ocean of data-intensive tasks – making the company one of the world’s top MySQL users.

A small army of Facebook MySQL experts will be converging on Santa Clara, Calif. next week where several of them are leading sessions at the Percona Live MySQL Conference and Expo. I had the chance to chat virtually with four of them about their sessions: Steaphan Greene, Evan Elias, …

The Percona Live MySQL Conference and Expo 2014 runs April 1-4  at the Santa Clara Convention Center and Santa Clara Hyatt – but be sure to get there a day early for the inaugural Open Source Appreciation Day on March 31 – this event is free but because space is limited I suggest registering now to reserve your spot.

Interest is particularly high in OpenStack and its intersection with MySQL and Open Source Appreciation Day and the conference sessions and events reflect this. Last year, the Percona Live MySQL Conference included 4 talks with Trove (“Red Dwarf” at the time) as the …
