InnoDB 1.1.0 has been released in MySQL 5.5
April 20th, 2010The InnoDB team is pleased to announce the availability of InnoDB 1.1.0!
InnoDB 1.1.x is based on the InnoDB Plugin 1.0.x.
InnoDB 1.1.x is included as the standard InnoDB in MySQL 5.5 and will not be distributed separately, thus we have decided to remove the word “Plugin” from its name.
InnoDB 1.1.0 includes the following enhancements, when compared with InnoDB Plugin 1.0.6:
- Faster recovery
- Multiple buffer pool instances
- Multiple rollback segments
- Extended change buffering with delete buffering and purge buffering
- Native Asynchronous IO on Linux
- Improved purge scheduling
- Improved log sys mutex
- Separate flush list mutex
- More stats in PERFORMANCE_SCHEMA
MySQL 5.5.4-m3, which includes InnoDB 1.1.0 can be downloaded from the MySQL 5.5 download page.
For more information see the Introduction to MySQL 5.5 and the InnoDB 1.1 manual.
Please report your comments and any problems or issues with the InnoDB in the InnoDB Forums or in the MySQL bug database.
We hope you will enjoy this new release of the InnoDB!
