Last week Tokutek announced that they’re open-sourcing their TokuDB storage engine for MySQL. If you’re not familiar with TokuDB, it’s an ACID-compliant storage engine with a high-performance index technology known as fractal tree indexing. Fractal trees have a number of nice characteristics, but perhaps the most interesting is that they deliver consistently high performance under varying conditions, such as when data grows much larger than memory or is updated frequently. B-tree indexes tend to get fragmented over time, and exhibit a performance cliff when data doesn’t fit in memory anymore.

The MySQL community is excited about having access to TokuDB’s source code, and rightly so. TokuDB is, broadly speaking, aimed at the same category of use cases as Oracle’s InnoDB, …

I have worked as an architect in the MySQL/NDB world for more than 20 years and I am still working at Oracle and I like it here. Given all the FUD spread about MySQL I thought it might be a good idea to spread the word about all the great things we're doing to MySQL at Oracle.

#1 We are working on improving modularity in MySQL code base
In the early days of MySQL the MySQL development had serious issues with its development model. It was a model designed for a small code base. I used to work at Ericsson which is developing telecom switches that have systems with tens of millions lines of code. Such large systems require modularity. The Ericsson switches was developed with modularity built into the programming language already since the 70's. Even with this modularity a second level of modularity was required. The learnings from this reengineering project that span over more than a decade has given me valuable insights …

With this version, the source code is now freely available under the GPL License v2. For more details, see our blog here. Open source pioneer Mozilla has been using TokuDB to manage its MySQL-driven Datazilla Data cluster, an open-source system for managing and visualizing performance data.

In the past TokuDB has been free for evaluation; the new TokuDB Community Edition extends free use to deployed environments. With this release Tokutek is also planning on making available a TokuDB Enterprise Edition, which includes technical support, initial customer onboarding services, and advanced tools for backup and recovery.

The Percona Live MySQL Conference & Expo 2013 was April 22-25 in Santa Clara, California. This was Percona’s second year organizing the conference and we were very pleased with the event and the feedback (check the #perconalive hashtag for a sampling of the great comments such as this from Tom Krouper or this from John Goulah or this from Jeremy Tinley or this from SF MySQL Meetup).

There are so many people involved with putting on this event that it’s impossible to list them all. The conference would be …

Those who are familiar with me know I've a dream.

5 years ago I decided to leave a systems integrator where I was doing great. Why? I wanted to be in a company with the same growth prospects that Oracle had in the 80s. I dreamed to be in the Oracle of 30 years ago and, as time travel wasn't affordable, I decided to join MySQL AB to help expand the business in Europe, the Middle East and Africa.
A few years later my dream came true, but in a slightly different sense. Sun acquired MySQL and was later swallowed by Oracle giving me the opportunity to join the company I wished I could have helped build.

Oracle is an amazing …

No need to say that as many others I have enjoy this conference a lot.

For me was also a personal success because I was finally able to have my company sponsoring the event and bring new members of my team to the conference as speakers, obviously all their merit, but I was happy as responsible of the MySQL cluster in Pythian knowing how much have cost to them to be there.

We also had a lot of people at the community dinner, last head count I did was over 120 people. In this regard I have to clarify some misunderstanding and confusion we had there.

Pedro’s requests to us to have the last head count by Tuesday morning, given that I have closed the count from the comments in the web-site and from the emails around noon.  The number I pass to Pedro’s base on that was of 70-80 people, but we had additional people registering after that time and also last moment show, given that we …

As Stewart mentioned in in post where-are-they-now-mysql-storage-engines : “Federated It’s still there… but is effectively unmaintained and dead. There’s even FederatedX in MariaDB which is an improvement, but still, the MySQL server really doesn’t lend itself kindly to this type of engine… it’s always been an oddity only suitable for very specific tasks.”

This post shows you how to move from a single instance Drupal/MySQL to a multi-server environment. A well designed multi-server deployment not only allows Drupal to scale, but will also enhance redundancy by removing single points of failure. Components used are Apache, PHP, csync2, lsyncd, Keepalived, HAproxy, MySQL Galera Cluster and ClusterControl.

Together with Sergei Petrunia, we talked about MariaDB Cassandra Interoperability. Sergei has done wonderful work here and I plan to showcase more Cassandra integration going forward. It’s worth noting that Elena came up with the benchmarks for this talk as well.
