A followup on SHOW ENGINE INNODB MUTEX
Employee +2 Vote Up -1Vote Down

In November, I wrote about the command SHOW ENGINE INNODB MUTEX and sought feedback as to how it continues to be used post introduction of performance_schema.

The outcome from this feedback is that the MySQL team has decided to remove this command from MySQL 5.7.

These decisions are not light ones for the team to make. I wanted to thank everyone for their feedback, and also share why this decision was an important one for the future of MySQL:

  • By design, data collection for SHOW ENGINE INNODB MUTEX was always enabled, with no switch to disable it. We believe that for some workloads being able to disable the collection is useful, and in the case of performance_schema this is possible.

    On the road again - FOSSAsia

    It has been a few busy months until now. I have moved from Italy to Thailand, and the move has been my first priority, keeping me from attending FOSDEM and interacting with social media. Now I start catching my breath, and looking around for new events to attend. But before I get into this, let’s make a few things clear:

    • I am still working for Continuent. Actually, it’s because of my company flexibility that I could move to a different country (a different continent, 6 time zones away) without much trouble. Thanks, Continuent! (BTW: Continuent is hiring! )
    • I am still involved with MySQL activities, events, and community matters. I just happen to be in a different time zone, where direct talk with

    MySQL Community Awards 2014: Call for Nominations!
    +1 Vote Up -0Vote Down

    The 2014 MySQL Community Awards event will take place, as usual, in Santa Clara, April 2014, during the Percona Live MySQL Conference & Expo (currently scheduled at Thursday, April 3rd 2014).

    The MySQL Community Awards is a community based initiative. The idea is to publicly recognize contributors to the MySQL ecosystem. The entire process of discussing, voting and awarding is controlled by an independent group of community members, typically based of past winners or their representatives, as well as known contributors.

    It is a self-appointed, self-declared, self-making-up-the-rules-as-it-goes committee. It is also very aware of the importance of the community; a no-nonsense, non-political, adhering to tradition, self criticizing

    SF MySQL Meetup Presentation: Changes in MySQL 5.7
    Employee +4 Vote Up -0Vote Down

    Last Wednesday, I spoke at the San Francisco MySQL Meetup on the topic of changes coming in MySQL 5.7 (and later).  We actually went through two different slide decks; the first on features being considered for deprecation in MySQL 5.7 (or later), and the second set providing a brief overview of the new features and benefits already introduced in MySQL 5.7 via the development milestone releases (DMRs) published to date.  A big thanks to the entire SF Meetup group, and in particular the organizers (Erin, Mike and Darren), for having me.  The event was streamed and recorded, and you can view the full presentation on YouTube.  The slide deck can be found here.

    Percona Live 2014 schedule released; BoF and Lightning Talks Call for Papers continues
    +0 Vote Up -0Vote Down

    The complete tutorial & session schedule for Percona Live MySQL Conference & Expo 2014 is released. This schedule offers both a sense of achievement as well as a sense of regret; for I believe the schedule is very good, and yet some good proposals had to be left out.

    This is an inevitable result of a conference that is popular and receives far more proposals than can fit within the time frames. This conference offers 96 session slots and 16 3-hour tutorial slots. We got well over 300 proposals -- I'm not even sure how to count them -- and they just can't all fit in. My sincere apologies to all those left out. A proposal of mine was just rejected yesterday from another conference; I can sympathize and

    Why a professional conference must have a committee, and what that committee does
    +3 Vote Up -0Vote Down

    What exactly is it that a conference committee does? This post comes as response to a comment on A sneak peek at the Percona Live MySQL Conference & Expo 2014, reading:

    Why the same committee each year? Community should vote on proposals and committee should just work schedule,etc.

    I'll pick the glove and shed some light into the work of the committee. While this specific comment related to the Percona Live conference, I trust that my opinions expressed below apply just as well to any (technical?) professional conference; the point below can equally apply to conferences from Oracle MySQL Connect, O'Reilly Velocity to FOSDEM & PyCon.

    I can sum up the entire answer with one word:

    Old and new MySQL verbosity
    +0 Vote Up -0Vote Down

    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.

    Call for papers (with lightning talks): Percona Live MySQL Conference 2014
    +1 Vote Up -0Vote Down

    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

    Forking MySQL/ for how long can forks keep up?
    +13 Vote Up -3Vote Down
    • 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

    MySQL 5.7.2 : Good job Oracle! (Well, almost)
    +5 Vote Up -4Vote Down

    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.

    PLUK Attendees: Show of hands
    +1 Vote Up -0Vote Down
    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
    Shi...pment happens - Tungsten Replicator 2.1.2
    +3 Vote Up -0Vote Down

    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

    Bristol MySQL Meetup & Holland Part II

    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.

    common_schema roadmap thoughts
    +0 Vote Up -0Vote Down

    I'm happy with common_schema; it is in fact a tool I use myself on an almost daily basis. I'm also happy to see that it gains traction; which is why I'm exposing a little bit of my thoughts on general future development. I'd love to get feedback.

    Supported versions

    At this moment, common_schema supports MySQL >= 5.1, all variants. This includes 5.5, 5.6, MySQL, Percona Server & MariaDB.

    5.1 is today past end of line, and I'm really missing the SIGNAL/RESIGNAL syntax that I would like to use; I can do in the meanwhile with version-specific code such as /*!50500 ... */. Nevertheless, I'm wondering whether I will eventually have to:

    Some of my MySQL Forge snippets are resurfacing
    +1 Vote Up -0Vote Down

    Some time ago, MySQL Forge went offline.

    As part of the Forge dismissal operations, I got a backup of my snippets from the MySQL community team, and I have been lazily looking around for an alternative place where to put them.

    I found such a place: Github GIST
    Gist is a simple way to share snippets and pastes with others. All gists are git repositories, so they are automatically versioned, forkable and usable as a git repository.

    Out of my 25 snippets, these are the ones that still look useful (at least, people have been asking me about those).

    RFC - DBdeployer : Bringing MySQL Sandbox to a new level

    MySQL Sandbox is growing old

    The MySQL Sandbox project has been around for 8 years, and it has gained considerable attention from the community. I have seen it mentioned in books and articles, used in other projects, and widely adopted by testers and bug reporters.
    I have used it for more than testing, and it has saved me many hours of labor by allowing me to create database servers in a few seconds.
    Yet, I have gathered a long list of grievance about it, both from my own experience and from other users feedback. Here goes.

    On contributing to MySQL
    +5 Vote Up -0Vote Down

    Dave Stokes has just written that MySQL is Looking for External Contributions. The first comments on that were negative, saying that forcing developers to sign a contributor agreement is not friendly, and that MySQL developers don't play well with external contributors.

    To be fair, it is not Oracle that has an unfriendly policy about contributions. It was already like this with MySQL AB, and the reason is simply that the company wants to maintain ownership of the code, so that it will be able to sell dual licensing agreements.
    I may not like it, but licensing was still a consistent part of the business when I left Oracle, and I assume it still is. Since this “feature” helps paying the developers that create open source software, I believe it is a
