This is a fantastic addition to the Percona team. Congratulations.

Vadim Tkachenko

Vadim Tkachenko co-founded Percona in 2006 and serves as its Chief Technology Officer. Vadim leads Percona Labs, which focuses on technology research and performance evaluations of Percona’s and third-party products. Percona Labs designs no-gimmick tests of hardware, filesystems, storage engines, and databases that surpass the standard performance and functionality scenario benchmarks. Vadim’s expertise in LAMP performance and multi-threaded programming help optimize MySQL and InnoDB internals to take full advantage of modern hardware. Oracle Corporation and its predecessors have incorporated Vadim’s source code patches into the mainstream MySQL and InnoDB products. He also co-authored the book High Performance MySQL: Optimization, Backups, and Replication 3rd Edition.


  • 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:


    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.
