Congratulations on this release!
Thanks!
About alpha status, well done! It shows that you have studied
software engineering!
Two questions:
* Do you have a policy for code contribution?
Yes please!
But seriously. I would really like to have code contributions. I am
very interested in putting this project on a broader community basis.
I consider PBXT to be "the community engine".
I am not sure of all the technical details though. Anyone interested
should contact me directly.
* Is there a publicly available bugs database?
Yes, on sourceforge.net:
http://sourceforge.net/projects/pbxt
Go to the Tracker menu, and then select Bugs. Here is the direct link:
http://sourceforge.net/tracker/?group_id=180250&atid=892419
Kind regards,
Paul
Cheers

Hi All,
I have just released the first fully durable version of PBXT.
Because of the amount of new code I have reverted PBXT to Alpha
status.
This version, 1.0-alpha, can be downloaded from: http://
www.primebase.org/download.
PBXT is a highly scalable, transactional storage engine for MySQL.
The main features are: multi-version concurrency control (MVCC),
ACID compliant, Referential Integrity and BLOB streaming (http://
www.blobstreaming.org).
The PBXT project is now owned and funded by PrimeBase
Technologies, an open source software development company. The web-
site, http://www.primebase.org, is also the new home of PBXT. Here
you will find all the information, documentation, downloads, and
links relating to PBXT.
I will also be talking about PBXT and BLOB streaming at the MySQL
Conference & Expo 2008 next month. It would be great to see you
there: http://en.oreilly.com/mysql2008/public/schedule/speaker/
517. Topics of my sessions include:
* Internals: How I made PBXT fully-durable.
* PBXT & SSD: Why this is a hot combination!
* BLOB streaming: How do you scale it?
Besides full durability, the latest release includes the following
improvements:
* Calculation of index statistics as required by the optimizer.
* New system variables (see http://www.primebase.org/
documentation#sysvar).
* Implementation of SELECT FOR UPDATE.
* Group commit.
* Support for SHOW ENGINE PBXT STATUS.
Note that this release does not have is an option to relax
durability. The transaction log is always flushed on commit. A
system variable to control the writing/flushing behavior of PBXT
will be added to the next release.
Don't forget to look me up at the conference!
Best regards,
Paul McCullagh
