  • State of InnDB Online DDL in MySQL 5.6.9-RC (good news included)

    December 18, 2012

    5.6.9-RC is out, and I was curious to see how the online DDL has improved since my 5.6.8 review. I also owe James Day this review, since he came up with results inconsistent with my own. We both agreed the dataset I was using was too small, but I got similar results even on larger […]

  • State of InnDB Online DDL in MySQL 5.6.8-RC

    November 20, 2012

    5.6.8-rc is out, and so I'm following up on InnoDB's online DDL new feature: the ability to SELECT, INSERT, DELETE, UPDATE a table even while an ALTER TABLE is executing on same table. The brief summary Not as advertised; many things can't be done. The longer review I'm using 5.6.8-rc 64bit binary distribution for Linux, […]

  • MySQL 5.6 RC: further thoughts and questions

    November 19, 2012

    Here are a few questions I came up with while experimenting with MySQL 5.6.7 & 5.6.8. They are the impressions of a first-time encounter with 5.6, which is a single opportunity for a person to point out the things that strike as odd. Bugs-wise, just submitted another crashing bug for 5.6.8. I'm just one man, […]

    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 […]

  • InnoDB DDL: kudos to quick responders on bugs.mysql.com

    October 18, 2012

    Continuing my experiments with 5.6 InnoDB online DDL, a bug which I've opened, and another which I commented on were quickly answered and explained by the Oracle/MySQL team. On both accounts I'm happy to acknowledge the issue is resolved; in both cases I failed to produce a real bug scenario. Good lesson. Kudos for quick […]

  • 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 […]

  • Thoughts on MySQL 5.6 new replication features

    October 15, 2012

    After playing a little bit with MySQL 5.6 (RC), and following closely on Giuseppe's MySQL 5.6 replication gotchas (and bugs), I was having some thoughts. These are shared for a few reasons: Maybe I didn't understand it well, and someone could correct me Or I understood it well, and my input could be of service […]

  • MySQL 5.6 new features: the user's perspective

    October 5, 2012

    This is a yet-another compilation of the new MySQL 5.6 feature set. It is not a complete drill down. This list reflects what I believe to be the interesting new features user and usability -wise. For example, I won't be listing InnoDB's split of kernel mutex. I'm assuming it can have a great impact on […]
