I was pleased to see Morgan’s announcement about a fix to an old problem of mine. In March 2012 I complained about MySQL verbosity during installation.

In MySQL 5.7.3, this behavior was changed. While the default is still as loud as it can, you can now add an option (log_error_verbosity) to send only errors to STDERR, which allows you to hide the output of mysql_install_db, and still get the errors, if they occur.

Well done!

However, the same obnoxious verbosity is also in MariaDB 10.0.x. Since I discussed this specific bug with a few MariaDB developers early in 2012, I was disappointed to see this same output when running mysql_install_db with MariaDB. Here’s the same appeal: MariaDB …

The call for participation for Percona Live MySQL Conference 2014 is still open. As part of the review committee, I will be looking at the proposals, and I hope to see many interesting ones.

There is a novelty in the submission form. In addition to tutorials and regular sessions, now you can submit proposals for lightning talks, to which I am particularly interested, as I have organized the lightning talks in the past two editions, and I am in charge to continue the tradition for the next one.

If you want to be a speaker at the conference, here are some tips to get your proposal accepted:

• Propose a topic that you know well;
• Take some time to write a well thought and meaningful proposal: nothing gets me faster to the rejection button than statements like “I want to talk about X, I will …

The CONNECT Storage engine implement the concept of a table made of multiple tables. These underlying tables can be distributed remotely. For example the underlying remote tables can be of ODBC or MySQL table type. this allows to execute distributed queries. What is nice is that we can execute this distributed query with parallelism.

Percona Live London 2013 is almost here: November 11-12 2013. Team MariaDB & SkySQL will be present, and here’s an agenda if you’re interested in all things MariaDB:

I am on my way to Argentina, where I will be speaking at the MySQL NoSQL & Cloud Conference & Expo.

I have two talks: one on my pet project MySQL Sandbox and one on replication between MySQL and MongoDB (using another project dear to me, Tungsten Replicator.

It’s my first visit to Argentina and I will try to look around a bit before the conference. And I look forward to see many ex colleagues and well known speakers at the conference. The lineup includes speakers from Percona, EffectiveMySQL, PalominoDB, MariaDB, SkySQL, Tokutek, and OpenStack.

I am looking forward to this trip. My presentation on MongoDB replication is a first for me, and I am always pleased when I can break new ground. I have the feeling that the networking is …

• Fact: MySQL 5.6 was released as GA in February 2013
• Fact: MySQL 5.6 has been available with its complete set of features since September 2012
• Fact: On September 21st, Oracle has released MySQL 5.7.2, which is the de facto major release after MySQL 5.6 (5.7.1 was just a token “we’re-still-in-business” release).
• Fact: As of today, there is no GA-ready fork of MySQL 5.6.

Percona Server is still in RC state, while MariaDB, with its runaway version 10, is still in alpha state. Of these releases, Percona Server seems the one in the better shape. Their problem was to adapt Percona Server to the enhanced codebase for 5.6, and the merging problems were bigger than the ones encountered in 5.1 and 5.5. Percona Server is a business oriented fork. It includes specific features for …

On September 21st, during the opening keynote at MySQL Connect 2013, Tomas Ulin disclosed the release of MySQL 5.7.2. This is a milestone release that includes several new features. Unlike the Previous one, which was just a point of pride, where Oracle was stating its continuous commitment to releasing new versions of MySQL. In MySQL 5.7.2, we see several new features:

• First and foremost, performance. The announcement slides say MySQL 5.7.2 is 95% faster than MySQL 5.6 and 172% faster than MySQL 5.5. I don’t know yet in which circumstances these numbers hold true, but I am sure someone at Percona will soon prove or disprove the claim.
• Performance Schema tables for several aspects:
  • …

It will soon be November and we'll be queuing up to register for the Percona Live conference once again. I spoke with some of this year's Percona Live London committee we all agreed that it would be great to arrange a community dinner if there was a community interest. In the past years of the PLUK conference there has not been a community event to attend in order to discuss sessions and make new friends. I for one love the `Pythian-arranged Community Dinner` at Pedro's that occurs annually in Santa Clara during the Percona Live Conference. I know that there are many attendees that do London and CA each year and wager that they'd agree that it's a great event. So lets have it... please r.s.v.p here and if the numbers are good enough we'll schedule something the evening of the tutorials. Please let me know of your interest in the comments below. Thanks :D

It was just a few days ago that we announced, with celebratory enthusiasm, Tungsten Replicator 2.1.1, and today we are at it again, with Tungsten Replicator 2.1.2.

What happened? In a surfeit of overconfidence, we released Tungsten 2.1.1, with faith on the test suite and its result. The faith was justified, as the test suite was able to catch any known problem and regression. The overconfidence was unjustified, because, due to a series of unfortunate events, some sections of the test suite were accidentally disabled, and the regression that was lurking in the dark was not caught.

Therefore, instead of having a quiet post-release week-end, the whole team has worked round the clock to plug the holes. There …

So just a quick note to express how great it felt to get the first MySQL Meetup in the UK's Bristol done. We had great enthusiastic attendees bringing their own curiosity about the product. We spent a couple of hours in conversation about a broad range of MySQL related topics. Amongst the points discussed were; MySQL Connect, Percona Live London, InnoDB vs. MyISAM, replication, query tuning and Ben gave a demo on pt-query-digest and pt-visual-explain. Although we touched many aspects it was really a primer for what we would like to achieve going forward. We're planning content and dates for the next meetup so keep an eye on the meetup page. I want to express that all comers are welcome whether you're fantastically experienced or a curious noob there's place for you. The group has already made many friends such as TomD from Percona, Stoker from Oracle and Marco from Pythian. …
