PBXT 1.0.11 Pre-GA Released!

Written for PBXT by Paul McCullagh on 2010-05-12

I have just released PBXT 1.0.11, which I have titled "Pre-GA". Going by our internal tests, and all instances of PBXT in production and testing by the community this is a GA version!

However, although PBXT has 1000's of instances in production, it is not used in very diverse applications. So I am waiting for wider testing and usage before removing the "Pre" prefix.

You can download the source code from http://primebase.org, or pull it straight from https://launchpad.net/pbxt. Here are instructions how to compile and build the engine with MySQL: http://primebase.org/download/#qg_source. PBXT builds with MySQL 5.1.46 GA (http://primebase.org/download/mysql-5.1.46.tar.gz), and earlier 5.1 versions.

If you don't want to compile it yourself, PBXT 1.0.11 will soon be available in the 5.1.46 release of MariaDB: http://askmonty.org/wiki/MariaDB:Download. And, for the more adventurous, PBXT 1.1 is included in Drizzle: https://launchpad.net/drizzle.

A complete list of all the changes in this version are in the release notes: http://primebase.org/download/ChangeLog.

If you are testing PBXT and have any questions send me an e-mail. I will be glad to help.

Otherwise, if you are looking for development or production support for MySQL/MariaDB and PBXT then please write to: support-at-primebase-dot-org. We are working together with Percona (http://www.percona.com) and Monty Program Ab (http://askmonty.org/wiki/Main_Page) to provide the service level you require.

PBXT 1.0.10 RC4 Released!

Written for PBXT by Paul McCullagh on 2009-12-29

This version add the pbxt_flush_log_at_trx_commit system variable. The value of this variable determines whether the transaction log is written and/or flushed when a transaction is ended.

A value of 0 means don't write or flush the transaction log, 1 means write and flush and 2 means write, but do not flush. No matter what the setting is choosen, the transaction log is written and flushed at least once per second.

All tests for this version run with MySQL 5.1.41.

PBXT 1.0.09 RC3 Released!

Written for PBXT by Paul McCullagh on 2009-09-10

This release includes a number of bug fixes and 2 Beta features:

- XA/2-Phase commit
- Online backup native driver (works only with MySQL 6.0).

According to our tests the Beta features do not affect the stability of the rest of the engine.

PBXT 1.0.08 RC2 Released!

Written for PBXT by Paul McCullagh on 2009-06-30

The second Release Candidate of PBXT, version 1.0.08, has just been released.

As I have mentioned in my previous blogs (http://pbxt.blogspot.com/2009/03/improving-pbxt-dbt2-performance.html and http://pbxt.blogspot.com/2009/03/solving-pbxt-dbt2-scaling-problem.html), I did a lot to improve the performance of this version.

At the same time I am confident that this version is stable as we now have a large number of tests, including functionality, concurrency and crash and recovery. But even more important, the number of users of PBXT has increased significantly since the last RC release, and that is the best test for an engine.

So there has never been a better time to try out PBXT! :)

You can download the source code, and selected binaries from here: http://primebase.org/download.

Vladimir and I have made a lot of changes, for details checkout the release notes (http://primebase.org/download/ChangeLog).

Bugs can be reported on Launchpad, here: https://bugs.launchpad.net/pbxt

There is also a new PBXT mailing list, https://launchpad.net/~pbxt-discuss, so if you have any questions this is the best place for them.
