At this week’s Oracle Open World show in San Francisco, Oracle made it clear they will continue to invest in MySQL.  

By unveiling the release candidate for MySQL 5.5, the company soothed any fears of what it what might happen to the world’s most popular open-source database due to the acquisition of Sun by Oracle.

“We continue to invest in MySQL technology and support the thriving MySQL user community,” said Edward Screven, Oracle’s Chief Corporate Architect.

Oracle even arranged an entire day at the event known as MySQL Sunday and hosted a party for MySQL aficionados. Clearly, getting rid of MySQL is not something Oracle is contemplating.

The new release candidate is said to boost performance and application scalability. It runs on Windows, Linux and Mac. Among the list of enhancements, MySQL Server and the InnoDB have been upgraded to work better on multi-CPU/core systems. In addition, InnoDB has been made the default storage engine for MySQL Server.

Replication has also come in for a facelift. Semi-synchronous replication is said to improve failover reliability. Replication Heart Beat deals with better detection, diagnosis and correction of synchronization issues. And improvements have been added to index and table partitioning.

In recent benchmarks using the release candidate for MySQL 5.5, compared to MySQL 5.1, results demonstrated marked performance improvements: According Oracle, the gains benchmarking MySQL 5.5 against v 5.1 on Windows showed up a performance leap of up to 1,500 percent performance for Read/Write operations. On Linux, a more modest 360 percent gain was realized.

“The availability of MySQL 5.5 release candidate is a testament to Oracle’s focus on helping users maximize the performance and reliability of critical application environments while reducing cost,” said Screven.

So Long OpenSolaris

Dan Roberts, Director of Solaris Product Management surprised attendees by stating that the OpenSolaris brand was going away. Although the name itself won’t continue, the source code will continue to be open and available to the developer community.

What Oracle is doing here, he said, is simplifying its naming conventions. “We are going to focus everything around Solaris 11 to keep it simple,” said Roberts. “There will no longer be a separate brand called OpenSolaris.”

He stressed that Oracle will continue to work with the Linux community on the open-source version of OpenSolaris, as well as Oracle Linux and its Red Hat Compatible Linux. “While we have changed the way we will work with the community, Solaris will remain open source and the source code will be made available to customers.”
