It fixes a lot of annoying bugs and upgrades the InnoDB plugin to version 1.0.7 for more performances.

Be careful : the MySQL server is now split in two separate packages :

  • mysql-server-core-5.1 that contains only the mysqld binary and some system files,
  • mysql-server-5.1 that depends on mysql-server-core-5.1 and that contains the init scripts and utilities to run the MySQL server in a Debian environment.

The migration to this new packaging schema is transparent and will not break any dependencies.

As usual, please read the changes in MySQL 5.1.46 and what’s new in the InnoDB plugin 1.0.7 before upgrading.

Two solutions exist :

  • using RDS, a “Database as a Service”
  • running your own MySQL server on a EC2 instance, with an EBS volume attached, a snapshot-enabled filesystem…

The comparison is made on features, cost and performances. I used the same MySQL version as RDS (5.1.42) and the same config. Performances are measured by tpcc-mysql from Percona and they are charted using Google Fusion Tables.

You’ll se that, altough MySQL + EC2 requires some additionnal DBA or sysadmin skills, it allows a lot of more tuning and a real performance boost (+270%).

So, if you’re planning to host MySQL databases on Amazon, feel free to take a look at these slides :

Note for french-speaking people : la présentation est disponible en français.

As usual, this maintenance release fixes a lot of bugs (please read the Changelog for more details).

Please note that the packaging is a little bit different from the official Debian packaging, to include the InnoDB plugin in the mysql-server-5.1 package instead of in the libmysqlclient-dev one. This plugin replaces the built-in InnoDB support and has many advantages :

  • fast index creation,
  • data compression,
  • new row formats,
  • new file formats,
  • performance and scalability enhancements…

You can easily enable it by uncommenting to lines in the /etc/mysql/my.cnf configuration file and then restart your MySQL server :

Editing my.cnf to enable the InnoDB plugin support

Please read carefully the InnoDB plugin documentation and backup your data before activating this beta quality feature!
