What is stored InnoDB buffer pool

Ever wonder what is stored in InnoDB buffer pool at the moment ?

It is not so hard actually – we made a short patch for MySQL 5.0 which show innodb buffer pool content

The binaries, RPMS (RedHat/Centos) and full source code also available to download

P.S. There is Jeremy Cole’s patch for InnoDB plugin MySQL 5.1, and main idea was taken from there.

    je vous remercie de partager, très gentil de votre part

  2. This is great! Can we expect to see this coming out in the Percona 5.1 binaries as well?

  3. Nils says:

    Is this patch also for the 5.0.68 Percona release available?

  4. Vadim says:


    I think in 5.1 we will include Jeremey Cole’s patch

  5. Vadim says:


    It is only for 5.0.67, will release for 5.0.68 later

    I am looking for a similar tool for the ibdata and ibd files – somethings that dumps page numbers and for each page tells me what the page is and does.

  7. Vadim says:


    It is on our todo, will implement it when we can :)
