Speed is important in all aspects of computing, especially with databases.
The latest 8.3 release of the open source PostgreSQL database has speed and a kind of heat of its own in mind. It's HOT, literally.
HOT is an acronym for Heap Organized Tuples (HOT),but according to PostgreSQL Core Team member Josh Berkus HOT in a word means performance. HOT is a key feature that PostgreSQL had on its to do list for 8.3 since the 8.2 release was finalized a year ago.
Beyond HOT there are a few other key highlights of the PostgreSQL 8.3 release including XML, full text search, and enumerated data type support improvements. There are also improvements to support data warehouses and the new release also has improved self-tuning features.
PostgreSQL has also changed the way it puts together its Windows version. PostgreSQL has been steadily improving its Windows versions since at least 2005 with the release of PostgreSQL 8.1.
"We've also moved to MS Visual C++ for Windows builds," Berkus commented. "While this was done primarily to improve performance and stability on Windows, I also hope that it inspires a few Windows developers to become code contributors."
PostgreSQL's new release comes as one its main benefactors, Sun Microsystems is in the process of acquiring the open source MySQL database for $1 billion.
Berkus is also a Sun Microsystems employee where he holds the role of PostgreSQL Lead. Sun has been backing PostgreSQL strongly since at least 2006. For the 8.3 release Berkus noted that his team at sun was working mostly on the Solaris build and compatibility issues.
"My team at Sun is working on stuff for 8.4, such as more SMP scaling (to 64 cores) and upgrade-in-place, but their wasn't ready in time for the May 2007 code cutoff for 8.3," Berkus commented. "So the largest chunk of code going into 8.3 was from EnterpriseDB."
Bruce Momjian, senior database architect, EnterpriseDB, and PostgreSQL Community Leader told InternetNews.com that for PostgreSQL 8.3 EnterpriseDB dedicated a team of developers on three continents to work on the project.. The plan is to do the same for 8.4.
With Sun's purchase of open source database rival MySQL now in motion, neither Berkus nor Momjian see much impact, yet.
"It's early days yet," Berkus said. "So far, the only thing we've done is to pick a common demo database to use with PostgreSQL, MySQL and Derby."
