Continuent, provider of commercial open source middleware solutions for database high availability, announced availability of Continuent Sequoia 3.0 Beta release. Continuent Sequoia is part of a suite of Continuent.org open source projects that deliver high availability for virtually any database environment.

This newest version of Continuent's Sequoia project, Continuent Sequoia 3.0, includes the more complete implementation of semantic information that supports not only stored procedures, but also views, triggers, and custom semantic for specific requests. The default group communication in Sequoia 3.0 is now Appia since it proved to offer better performance and stability than JGroups, which is still available as a second choice.

Macro handling has changed to be now fully customizable for any database specific macros. New user-based access control per virtual database provides fine grain ACL at the cluster level. New versions of the manuals are also available including a new 'concept' guide.

"Continuent Sequoia 3.0 is a milestone release “ said Emmanuel Cecchet, Continuent open source lead. "This release directly benefits from all the experiences gained in major customer pilot projects and deployment bringing Sequoia to the highest level of reliability."

"The upcoming Continuent uni/cluster 2007 will be based on Sequoia 3.0. " said Pascal Bresson, Continuent Director of Engineering and Product Management.
