The InnoDB team is pleased to announce the availability of InnoDB Plugin release 1.0.6.

Changes since release 1.0.4 include a number of bug fixes and improvements, of which the most noticeable are:

• Users can now limit the impact of a full scan (such as done by “mysqldump” or creating an index) on other operations by adjusting the way scanned pages enter the buffer pool.
• Duplicate table names are now reported to the client connection instead of the server error log.
• CREATE INDEX can now be interrupted.

This page descrbes how the buffer cache behavior can be tuned to reduce the impact of a full scan on ongoing operations, and presents some performance data from a simple test.

This release is a jump from the previously available InnoDB Plugin, release 1.0.4. Sun distributes with MySQL V5.1.41 an intermediate release of the InnoDB Plugin (release 1.0.5), a different option for you to use with that release of MySQL. InnoDB Plugin release 1.0.6 differs from 1.0.5 with the addition of several bug fixes.

For a full list of changes see the InnoDB Plugin Change History or the online ChangeLog.

Source code and binaries for the InnoDB Plugin 1.0.6 can be downloaded from the download page. This new release will work with MySQL releases 5.1.24 and up when built from source. Binaries have been compiled for MySQL 5.1.41 and can be plugged in dynamically only in that version.

Please report your comments and any problems or issues with the InnoDB Plugin in the InnoDB Plugin Forum or in the MySQL bug database.

We hope you will enjoy this new release of the InnoDB Plugin!
