Yasufumi Kinoshita joins Percona

Posted by Vadim |

I am happy to announce Yasufumi Kinoshita joins our team as Performance Engineer. Yasufumi is known as InnoDB hacking expert, and there is bunch of patches he made we include in our releases: innodb buffer pool scalability fix, innodb rw_lock fix, control InnoDB IO etc. Actually there is one more patch -
“adaptive flush” in InnoDB, which makes flushing process more uniform and predictable. Yasufumi will post about this patch soon.

Yasufumi also had talk on MySQL Conference & Expo 2007
InnoDB Performance Potential in High-end Environments

Yasufumi’s primary tasks as you can guess will be InnoDB performance and scalability fixes, InnoDB improvements and related question, however we are not going to restrict his activity only to InnoDB area but for all MySQL related problems.

So expect more and better patches in near future.

    There was comment from Mark Callaghan, by some reason our blog filtered it out:

    Welcome, Yasufumi. This is great news as Yasufumi was the first in the community to identify and fix the scalability problems in Innodb. Now I expect even more great work.

    Seems you have more hackers working on InnoDB at Percona than Oracle.

    Are those guys still in business?

    They get about 20 posts per months on their forums.

    An outsider might interpret that they don’t understand Open Source.

    Congratulations to both Yasufumi and Percona!

    It is a pleasure to see Yasufumi joining the MySQL/InnoDB ecosystem. Yasufumi has written several patches to improve InnoDB’s scalability and has tracked down a serious bug in InnoDB-5.0.30 rw-lock implementation.

    To Kevin Burton I would like to assure that Innobase/Oracle has 8 developers working on InnoDB. We spend quite a lot of time handling the bug reports on InnoDB and InnoDB Plugin:

    http://bugs.mysql.com/search.php?search_for=&bug_type%5B%5D=Server%3A+InnoDB&bug_type%5B%5D=Server%3A+InnoDB+Plugin&status%5B%5D=Active&severity=&priority=all&showstopper=&limit=All&order_by=id&direction=DESC&cmd=display&phpver=&os=0&os_details=&bug_age=0&tags=&similar=&target=&defect_class=all&workaround_viability=all&impact=all&fix_risk=all&fix_effort=all&assign=&reviewer=&lead=&verifier=&qaverifier=&qareviewer=&actionby=&metrics_ref=&affectscustomer=&mysqlnetwork=&qatestneeded=&qareviewneeded=

    We are today working towards the release of InnoDB Plugin 1.0.2. The InnoDB Plugin contains major new features like transparent zip compression of tables, and fast index creation.

    We are also working with Google engineers on scalability patches to InnoDB.

    Best regards,

    Heikki Tuuri
    Innobase Oy
    Oracle Corp.
