Due to summer vacations - yes, even we take some time off - our release-cycle has slowed down quite a bit so it has already been more than 4 weeks since we aired an update of Workbench. Right in the middle of testing and preparing the next build, our build-server has raised the white flag. Looks like the cooling system above the unit decided, that its too hot, and put a cold shower right down on our machine. Our engineers are quickly gathering some new iron and we are meanwhile preparing the build manually this time. There are a few bugs remaining but next package will be ready soon and we put it on our download servers - so stay tuned for the next Workbench 5.0 release.

So, the Malta MySQL User Group has had its first ever meet-up today, and it was a success! When organizing it, I had no clue how many people would show up, people have said “yes” and then changed to “no”, and vice versa.

Anyway, so the morning came, and I sent out a few confirmation emails, and it suddenly dropped down to just three of us, which was a shame. Anyway, around 5pm, I noticed that there was four more that had just said they wanted to attend. Unfortunately, one of those dropped out, but it was still a great turnout.

This is a great opportunity for us to promote MySQL use in Malta, as well as share experience and knowledge. Also just to network a bit.

So, this time, for meeting #1, we met up outside a local bank, and walked to Il-Mithna, which is a local restaurant. In this picture, there is the first core group of local user group members, all happily gathered and just about to start our discussions. …

We are quickly approaching opening up the MySQL Query Analyzer for general beta and I wanted to pass along an open invite to the following related and informational events.

On 8/13, I will be doing a micro level presentation on MySQL Enterprise. Please attend and learn more about the database software, monitoring and advisor services and support solutions that make up a subscription. I plan to do a demo of the Enterprise Monitor and the new Query Analyzer; that alone makes attending worth the price of admission (in this case 45 minutes of your time!). Learn more and register here.

On 8/20, I will be doing a presentation on the new Query Analyzer. This will be a technical discussion around how DBAs monitor for bad queries now and how the Query Analyzer makes the job much easier. This will be a good time to learn about getting in …

Why may LIMIT only take a fixed number? Not even a user variable, let alone an expression.

Wouldn't it be useful to set a user session variable that always gets applied as an implicit limit value?

Both of these things could be done in Drizzle.

Since 2006 H1 I've been working on benchmarking MySQL
Cluster using the DBT2 test suite. Initially this meant
a fair amount of work on the test suite itself and also
a set of scripts to start and stop NDB data nodes, MySQL
Servers and all the other processes of the DBT2 test.
(These scripts and the DBT2 tests I'm using is available
for download at www.iclaustron.com)

Initially I worked with an early version of MySQL Cluster
based on version 5.1 and this meant that I hit a number
of the performance bugs that had appeared there in the
development process. Nowadays the stability is really good
so in the most case I've spent my time focusing on what
is required to use in the operating system and the
benchmark application for optimum scalability.

Early on I discovered some basic features …

What a week!

First off, here are the slides from my talk “CouchDB at 10,000ft”. Thanks to everyone who showed up and a double thanks for the eight of you who rated my session so far. More special props to the ones with constructive criticism. I’ll do better next time. If you haven’t already, place your vote.

Ted has some nice pictures of my talk and the discussion afterwards. The feedback I got was great and people do really want to use CouchDB. This is great encouragement for putting in some after-work hours to push things towards 1.0.

But OSCON.

Hi!
It has been very hot recently.  Please take good care of yourself.

Today, I would like to deliver a tip for “MySQL Storage Engine”, which was written by Mikiya Okuno, MySQL Senior Technical Support Engineer.  Are you familiar with storage engine?  Let’s learn about the storage engine together!

************************************
MySQL is so popular and used for various applications.  One of the reasons is its flexibility which is achieved by a technology called the “Storage Engine”.  The storage engine is an essential concept to MySQL.

MySQL utilizes virtualized and abstracted layers which can be switched per table.  These layers are the storage engine.  MySQL brings out high performance by switching depending on application’s requirements and data access pattern.  The storage engine is one of the most important elements and attracting a lot of …
