I wasn’t at the MySQL Conference this year but it was very nice to follow this event from Paris.
Of course I didn’t feel the general atmosphere by visiting booths or met fabulous people.
But it was a great opportunity to offer you a live post about the conference with an external point of view.

Twitter, RSS feeds (yes Google, I still use RSS), Planet MySQL and infiltrators were my best friends during this crazy week.

I would like to summarize the major announcements and events occurs during this tenth edition.

As you may know, I'm a big fan of JSON and I am working on releasing a new version of my JSON tools real soon. Meanwhile on the SkySQL Solutions Day on April 26 I gave a talk on JSON with MySQL and MariaDB, and the slides are available on slideshare.

MySQL Connector/Net 6.7.2, a new version of the all-managed .NET driver for MySQL has been released.  This is the first beta release intended to introduce users to the new features in the release.  This release is feature complete, it should be stable enough for users to understand the new features and how we expect them to work.  As is the case with all non-GA releases, it should not be used in any production environment.  It is appropriate for use with MySQL server versions 5.0-5.7.

NetMotion Wireless had used Microsoft SQL Server with Mobility Analytics, their mobile VPN product’s analytics module, but found it was too costly and lacked the platform and language flexibility to be a good [embedded] database. As a result, when the NetMotion Wireless product team was developing Locality, a cellular network management product, they decided to find an …

Baron has an interesting post about TokuDB. I agree with him that open-source TokuDB can be a big deal. I compared it with InnoDB using linkbench and the results are interesting. I used pure-disk servers with 1B rows in the link table (maxid1=1B), zlib compressed InnoDB tables and lzma compression for TokuDB. After running the test for a few days InnoDB used 710 GB on disk and sustained 501 QPS compared to 359 GB and 1147 QPS for TokuDB. 

TokuDB was marketed and perhaps even designed with pure-disk servers in …

We’ve told you all about MySQL mult-master replication’s limitations. If you write to two masters it is bound to fail for myriad reasons. Now what? Do what the pros do that’s what. A. Don’t write to both masters Using multi-master replication works great as long as you do so in active-passive mode. Never write to [...]

Software Carpentry is running a 2-day software skills boot camp in Boston, June 24-25th 2013, for women in science, engineering, medicine, and related research
areas. Registration is $20.

Boot camps alternate short tutorials with hands-on practical exercises. You are taught tools and concepts you can use immediately to increase your productivity and improve confidence in your results. Topics covered include the Unix shell, version control, basic Python programming, testing, and debugging — the core skills needed to write, test and manage research software.

This boot camp is open to women at all stages of their research careers, from graduate students, post-docs, and faculty to staff scientists at hospitals and in the public, private, and non-profit sectors.

When you setup a monitoring system for SQL Server, you often use thresholds to determine when an instance is healthy. You might say that you want to be alerted when CPU use is over 90% or when there’s only 10% of disk space left. The trouble with these thresholds is that they will often throw off false positives, or send you an alert when really nothing is wrong. Simple thresholds often have to be tuned to the individual instance, since a server with 10 TB still has 1 TB of space left at 90% disk use.

Baron Schwartz blogged about this issue in an article and he’s been creating software that monitors MySQL beyond simple thresholds, after stating that they do not work in most cases. He makes a good …
