Enhancements in Performance, Availability, and Usability Underscore Oracle’s Continued Investment in MySQL
- Continuing to deliver new innovations to MySQL,
Oracle today announced the availability of the release candidate for
MySQL 5.5, the world’s most popular open-source database, licensed under
the GNU General Public License (GPL).
- Announced during the first MySQL Sunday
event at Oracle OpenWorld, the MySQL 5.5 release candidate showcases
the latest enhancements in performance and scalability, availability and
Enhances Capabilities for Business Applications
MySQL 5.5 release candidate helps improve the performance and
scalability of applications across multiple operating environments,
including Windows, Linux, and Mac. Enhancements include:
MySQL Server and InnoDB have been enhanced to provide optimum
performance and scalability when running on the latest multi-CPU and
multi-core hardware and operating systems.
InnoDB is now the default storage engine for MySQL Server, delivering
ACID transactions, referential integrity, and crash recovery.
New semi-synchronous replication improves failover reliability by
allowing the master to proceed without waiting for all the slaves to
acknowledge. Once one slave acknowledges, the transaction can be
committed. This also helps improve data integrity.
Replication Heart Beat enables faster detection, diagnosis and
correction of master/slave synchronization issues, helping improve the
reliability and availability of data by reducing the risk and impact of
master/slave synchronization issues.
Improved index and table partitioning enables RANGE and LIST
partitions to be defined on date, datetime, varchar, and char columns,
simplifying and extending MySQL and adding flexibility to indexing and
- DBAs and developers
can save time using the ANSI/ISO standard SIGNAL/RESIGNAL syntax inside
stored routines, including triggers, to raise an error condition
invoking specific error handling within their applications.
Enhanced diagnostics, including a new ERFORMANCE_SCHEMA, provide
low-level diagnostics on MySQL server performance statistics, allowing
DBAs to pinpoint resource-intensive processes and events, streamlining
efforts and helping to enhance their productivity.
MySQL 5.5 Release Candidate Demonstrates Significant Performance Gains in Real-World Tests
recent benchmarks using the release candidate for MySQL 5.5, compared
to MySQL 5.1, results demonstrated marked performance improvements:
- On Windows: up to 1,500 percent performance gains for Read/Write operations, and up to 500 percent gain for Read Only(1).
- On Linux: up to 360 percent performance gain in Read/Write operations and up to 200 percent improvement in Read Only(2).
“We continue to invest in MySQL technology and support the thriving
MySQL user community,” said Edward Screven, Oracle’s Chief Corporate
Architect. “The availability of MySQL 5.5 release candidate is a
testament to Oracle’s focus on helping not only LAMP users, but also
Windows users maximize the performance and reliability of critical
application environments while reducing cost. Oracle now has two
superior database alternatives to SQLServer, both delivering better
value and broader platform support to end users and ISVs.”
“I’m really blown away by MySQL 5.5‘s improvements,” said Don
MacAskill, CEO, SmugMug. “You can now have a whopping 128K transactions
in flight. Best of all, it’s far more performant than it used to be.
Thank you Oracle!”
