  • 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 […]

  • 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 […]

  • Experimenting with 5.6 InnoDB Online DDL (bugs included)

    October 18, 2012

    MySQL 5.6 offers the groundbreaking online DDL operations for InnoDB. Most common use cases will enjoy this feature, and the need for online alter table scripts will decrease. This is a killer feature! I've put this new feature to the usability test. How did it go? Not too well, I'm afraid. [Updates to this text […]
