    A technical WebScaleSQL review and comparison with Percona Server
    +1 Vote Up -0Vote Down

    The recent WebScaleSQL announcement has made quite a splash in the MySQL community over the last few weeks, and with a good reason. The collaboration between the major MySQL-at-scale users to develop a single code branch that addresses the needs of, well, web scale, is going to benefit the whole community. But I feel that the majority of community opinions and comments to date have been based on the announcement itself and the organizational matters only. What we have been missing is an actual look at the code. What actual new features and bug-fixes are there? Let’s take a

    Per query variable settings in MySQL/Percona Server/WebScaleSQL
    +1 Vote Up -0Vote Down

    Recently there was a discussion on the webscalesql mailing list started by Chip Turner on a proposed change to the MAX_STATEMENT_TIME patch. This feature has been known as per query variable settings (WL#681) and even shipping in Percona Server 5.6 as per-query variable statement.

    This feature has piqued my interest since 2009, when the MySQL project (then owned by Sun Microsystems) participated in Google Summer of Code 2009, and we

    There are many MySQL related IRC discussion channels as the ecosystem itself grows. I join the following. Are there any that I’m missing?

    Freenode (irc.freenode.net):

    • #mysql – main channel for all kinds of end user MySQL related discussions (the noisiest of the lot, naturally)

    • #webscalesql – for all kinds of WebScaleSQL discussions
    • #percona – main channel for all kinds of Percona related discussions

    +1 Vote Up -0Vote Down

    Madrid MySQL Users Group will have its next meeting on the 24th of April. Details can be found on the group’s Meetup page.

    We plan to talk about WebScaleSQL and I will give a short presentation on how to build WebScaleSQL RPMs on CentOS 6.  The meeting will be in Spanish.

    We’ve changed the place that we’ll be holding the meeting. See the Meetup URL for details. Looking forward to seeing you there.

    WebScaleSQL on Windows? I wish, but not quite yet, it seems …
    +1 Vote Up -0Vote Down

    For fun, I tried building WebScaleSQL on Windows, even though it’s not [yet?] a support platform.

    Using the following (as I would to build MySQL/MariaDB):

    cd c:\mysql\webscalesql-5.6.16
    mkdir bld
    cd bld
    cmake ..
    cmake --build . --config relwithdebinfo --target package

    I end up with:

        238 Warning(s)
        110 Error(s)
    Time Elapsed 00:05:08.53

    Looking through the output, the main error is this:

    fatal error C1083: Cannot open include file: 'atomic':
    No such file or directory

    Of course the directory does exist, and permissions are correct.

    C:\mysql\webscalesql-5.6.16\include\atomic_stat.h contains the following line:

    #include <atomic>

    And this exists:

    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.

    WebScaleSQL RPMs for CentOS 6
    +0 Vote Up -0Vote Down

    Looks like this post was rather unclear. See the bottom for how to build the rpms quickly.

    WebScaleSQL was announced last week. This looks like a good thing for MySQL as it provides a buildable version of MySQL which includes multiple patches from Facebook, Google, LinkedIn, and Twitter needed by large users of MySQL, patches which have not been incorporated into the upstream source tree.  Making this more visible will possibly encourage more of these patches to be brought into the code sooner.

    The source is provided as a git repo at https://github.com/webscalesql/webscalesql-5.6 and as detailed at http://webscalesql.org/faq.html the documentation says there is currently no

    When the Innovator's Dilemma hit the MySQL World

    What’s the connection between databases and fruit flies?
    Some of you may be familiar with the bestseller in business literature The Innovator's Dilemma: When New Technologies Cause Great Firms to Fail, by Harvard professor Clayton Christensen. In his book, Prof. Christensen compared disk drives to fruit flies. The comparison relates to the rapid changes that disrupted the disk drive industry for decades. That disruption is compared to the rapid changes that take place to fruit flies that live only for few hours, and for this reason researchers can study and analyse their behaviour.

    In the software business, you can replace disk drives with databases. Obviously, databases live longer than fruit flies, but it is an industry that sometimes shows schizophrenic changes. Whilst it is true that relational databases have being dominated the

    MariaDB and WebScaleSQL
    +2 Vote Up -0Vote Down

    On Thursday MySQL technology saw a huge boost. It’s hard for anyone now to argue that MySQL isn’t in the game of extreme scalability and performance, which some NoSQL vendors have been using as a tagline for the last years. To see four of the largest MySQL and MariaDB users come together to bootstrap a branch of MySQL for extreme scaling needs is simply fantastic. The improvements done inside these companies will now be available to the rest of the community. In all fairness Facebook and Twitter, in particular, have been making their improvements publicly available also before. Google has also made some improvements available publicly over the years and have lately been active in the MariaDB project with code reviews, bug fixes and other patches. But broadening the public contributions further and combining it all, is new.

    Engineering of MySQL technology happens in many places. Aside from
