XtraDB storage engine release 1.0.6-9


Dear Community,

As of today Release 9 of XtraDB storage engine is available.

The release includes following new features:

  • The release is base on 1.0.6 version of InnoDB plugin.
  • MySQL 5.1.42 as a base release
  • Separate purge thread and LRU dump is implemented (this feature was actually added in Release 8, but somehow it was forgotten)
  • New patch innodb_relax_table_creation
  • Added extended statistics to slow log
  • Adjust defaults with performance intention
  • Added parameter to control checkpoint age
  • Added recovery statistics output when crash recovery (disabled by default)
  • Patch to dump and restore innodb_buffer_pool

Fixed bugs:

  • Bug#488315:
    rename columns and add unique index cause serious inconsistent with mysqld
  • Bug #495342: “MySQL 5.1.41 + InnoDB 1.0.6 + XtraDB patches extensions-1.0.6, rev. 127 fails to compile on OpenSolaris”
  • Bug #47621: change the fix of http://bugs.mysql.com/47621 more reasonable

    I started to use your repo seems very handy, thank you!

    There are Percona-XtraDB-* and MySQL-*-percona packages.

    What is the difference? Percona-XtraDB-* is a separated project or it’s a development version or the MySQL-*-percona packages?
