  • Converting from TokuDB ( Mysql 5.5.30 ) to Percona Server ( 5.6 )

    I'm currently using TokuDB. Unfortunately we're having some big issues with it including data loss/corruption in our production server.

    I'm wondering what is the correct ( and fastest ) way to move from TokuDB to Percona. My first thought is:

    1) Change all tables from TokuDB to InnoDB.
    2) Stop TokuDB
    3) Start Percona with a similar Mysql version ( 5.5.30 )
    4) Check if everything is OK
    5) Upgrade Percona to 5.6

    Is this the fastest way?

    While doing the initial tests on a development server the first step takes a long time. Currently our database uses ~500GB.

    Thanks for any tips.

    The plan looks good to me. In order to make alter faster I would try with pt-online-schema-change - there is a chance it would be faster.

    However, I am curious what exact problems did you encounter with TokuDB? Did you file bug reports about them?
