  • Three wishes for a new year

    September 23, 2014

    Another new year by Jewish calendar. What do I wish for the following year? World peace Good health to all Multi-core execution for queries After having evaluated a few columnar databases, and having seen how a single query gets 24 cores busy, I can't look at MySQL the same way again. The fact that a […]

  • Some anecdotes I learned at Percona Live

    April 8, 2014

    While on the plane back home I wrote down all my impressions from Percona Live 2014. Have lots of TODOs and great ideas to implement. Among all my impressions, there were a few anecdotes worth noting. 5.6 GTID is still unfriendly. It will require complete shutdown & reconfiguration of your entire replication topology; and some […]

  • Why delegating code to MySQL Stored Routines is poor engineering practice

    February 6, 2014

    I happen to use stored routines with MySQL. In fact, my open source project common_schema heavily utilizes them. DBA-wise, I think they provide with a lot of power (alas, the ANSI:SQL 2003 syntax feels more like COBOL than a sane programming language, which is why I use QueryScript instead). However I wish to discuss the […]

  • Why a professional conference must have a committee, and what that committee does

    December 14, 2013

    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 […]

  • 5 years of blogging

    October 22, 2013

    openark.org blog is now five years old. Hurrah! Throughout these five years I posted almost exclusively MySQL oriented blogs, though I had every intention of writing on various engineering topics. I still see blogging as one of the most important forms of knowledge sharing, and indeed for me the blogs aggregated at Planet MySQL are […]

  • Percona Live 2013 keynotes: followup questions and discussion

    April 28, 2013

    Here are a few questions remained open for me from Percona Live 2013 about things that have been said during keynotes; I will appreciate a discussion on comments. Here goes: Question #1 Brian Aker (HP) asks Simone Brunozzi (Amazon) what the underlying technology for DynamoDB is. Simone says can't disclose. Brian says: "it's MySQL!!". Simone […]

  • Sessions of interest in Percona Live 2013

    February 5, 2013

    Percona Live 2013 is shortly upon us, and it might be a good idea to watch for what's ahead of us. Talks of interest There is no way I can do justice to all. I wish to point out a small number of sessions I am personally interested in attending. I will not be able […]

  • Notes on "5 Tips for migrating your MySQL server to a Galera Cluster"

    December 17, 2012

    This post comes as response to 5 Tips for migrating your MySQL server to a Galera Cluster by Henrik Ingo (Galera), which is a good read. This post is a bit lengthy which is one of the reasons why I didn't just comment on said post. The Galera talk in London was indeed well crowded, […]

  • My take on privatized MySQL security bugs

    November 8, 2012

    A couple weeks ago I submitted BugĀ #67315: Crashing server by stored function referencing user defined variable in query. If you press that link, you can't see the bug (though I can as I submitted it). This is due to Oracle's policy for security-related bugs. Tomas Ulin, Vice President MySQL Development at Oracle , was kind […]

  • Further experiments with MySQL 5.6.7-RC: submit your bugs

    October 22, 2012

    Here's the background: I'm testing many features of MySQL 5.6.7-RC due to two reasons: I'm verifying my common_schema installs and works properly on 5.6 I promised I would present a 45 minute "what's new in MySQL 5.6" seminar in the upcoming OracleWeek (Israel) In the case of common_schema, I have managed to find one weird […]
