I have just released PBXT 1.0.09 RC3. Besides bug fixes (details in the release notes), this version includes 2 Beta features:

• XA/2-Phase Commit support
• Native online backup Driver

XA support has been around MySQL for quite a while, and we all know of it usefulness, for example when sharding. So I was surprised to find a bug in the XA recovery: Bug #47134. Contrary to what is reported, the crash can also occur when using XA with just the default engines installed, so watch out for that one (the good news: the bug fix is simple).

Online backup is really cool! I have heard that it may soon be released in a coming version of 5.4, so lets hope that this is true.

In a little test, I did a backup of a 10GB database in 49.26 seconds! …

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

As I have mentioned in my previous blogs (here and here), I did a lot to improve performance for this version.

At the same time I am confident that this release is stable as we now have a large number of tests, including functionality, concurrency and crash 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: …

With all the booha about MySQL not being ready for GA, it makes me almost afraid to announce, ahem, ... and PBXT is, ehr, RC.

It has been just over a year now since I started developing the fully durable version of PBXT. Before that, PBXT was Beta. After that, it was Alpha again.

Now we have 2 solid Beta versions behind us, Vladimir and I have fixed all known bugs for this version, including quite a number of foreign key bugs. We have all 259 mysql-test-run tests that were adapted for PBXT (and a bunch of our own) running through without any errors on 4 platforms: Mac OS X, Linux 32-bit and 64-bit, and Windows. Our buildbot is giving us a green light, at last!

Besides this we have done crash tests, load tests and crash and load tests (I mean recovery)! And maybe most important, we have it ticking away in a very demanding OEM product …

There are a few small changes in MySQL 5.1.29.
SHOW PROFILESIt was already in a preview, but now SHOW PROFILES is available in 5.1 binaries. As you may recall, it is not active …

I am pleased to announce that the Beta version of PBXT has just been released. You can download the source code of the storage engine from www.primebase.org/download. I have also updated the documentation for this version.

Configuring and building the engine is easier than ever now. To configure PBXT all you have to do is specify the path to the MySQL source code tree (after building MySQL), for example:

./configure --with-mysql=/home/foo/mysql/mysql-5.1.26-rc

The PBXT configure command will retrieve all required options from the MySQL build. For example whether to do a debug or optimized build and where to install the plugin are determined automatically, depending on how you configured MySQL.
