MySQL Table Sync 0.9.2 is a bug-fix release. Since the last release users have reported several bugs. I am still postponing new features until after the MySQL Conference and Expo, because I am focusing on the innotop session I’ll be presenting at the conference. I have also created a new mailing list on sourceforge for discussing all things MySQL Toolkit. Thanks to a user for suggesting the mailing list – I needed a nudge.

About three years ago I implemented the myhttp engine. It is one
of about three engines I wrote for 4.1 that I never made
public.
If you have seen the example I gave at Google a couple of years
ago, ha_giggle, this is the engine that it was based on (and it
was the base for Mark's AWS
Engine as well). Its a very basic engine that implements
SELECT, INSERT, and DELETE... or as we call them in the web
sphere, PUT, GET, and DELETE.
Just as an example you can do the following:
mysql> CREATE TABLE `d` (`a` varchar(125), b text, primary
key(a)) ENGINE=HTTP DEFAULT CHARSET=latin1 CONNECTION="http://en.wikipedia.org/wiki/";
What can you do from this? You can SELECT pages from wikipedia
:)
For INSERT to work you need a webserver that support PUT …

It’s strange what articles on one’s site become “popular.” I wrote Non-technical Guide to Isolating Slow MySQL Queries some time ago when I was an internal system admin at a data center. I wasn’t “customer-facing” but I still got requests from customers who wanted me to look at their MySQL server. Since that wasn’t my primary responsibility, I had to enlist their help to save me time. Hence, I wrote this article to help not-technically-inclined customers through the first few steps.
My webstats have shown this page to be hit more often than I would have expected. Consequently, I felt that I should update it, so I did.

It's been a long time coming, but we've finally managed to get the first alpha release of Connector/J 5.1 out the door. The key thing in this release is support for JDBC-4.0, including:
Ease-of-development features including auto-registration with the DriverManager via the service provider mechanism, standardized Connection validity checks and categorized SQLExceptions based on recoverability/retry-ability and class of the underlying error.
Unwrapping to interfaces that include vendor extensions
Support for XML processing via JAXP interfaces to DOM, SAX and StAX
Support for setting per-connection client information (which can be viewed in the comments section of a query via "SHOW PROCESSLIST" on a MySQL server, or can be extended to support custom persistence of the information via a public interface)
Support for JDBC-4.0 NCHAR, NVARCHAR and NCLOB types
It's available for download now at …

MySQL-Storage-Engines für memcached und Amazon S3
Neue Storage-Engine-Architektur animiert Entwickler
Mit seiner neuen "Pluggable Storage Engine Architecture" bietet MySQL 5.1 eine neue Flexibilität in Sachen Storage-Engines und einige Entwickler zeigen, was sich mit diesem System anfangen lässt: Mark Atwood arbeitet beispielsweise an einer Storage-Engine, mit der sich über MySQl auf Amazons Webspeicherdienst S3 zugreifen lässt, und Brian Aker bietet Zugriff auf Dankas memcached via MySQL.
Mit seinen verschiedenen Storage-Engines und deren unterschiedlichem Funktionsumfang hebt sich MySQL von manch anderem Datenbank-Management-System ab. Während eine Storage-Engine mit Volltext-Indizes aufwartet, bringt eine andere Transaktionsunterstützung mit. Was manche als Schwäche des Systems sehen, versucht MySQL zu einer Stärke zu machen und führt mit MySQL …

So a few things happened in the last few weeks or will be happening that I find worth sharing. First up Pagenello, the biggest Ultimate Frisbee tournament in Europe, was blast. Plenty of sun while playing 10 beach Frisbee matches in 4 days with some quality time chilling in Rimini before and after the tournament.
Yesterday I also held a slightly updated version of my "Explaining Explain" talk (now called "Finding Order in Execution") at the webtuesday usergroup meeting here in Zurich. As always you can find a pdf with the slides in the slides section of my blog.
Speaking of speaking I will be giving a talk on PHP6 at MySQL User …
