MariaDB in Greece

I suppose I should probably say “MariaDB στην Ελλάδα” which, according to Google Translate, is Greek for “MariaDB in Greece”. We’re still finalizing the arrangements, but I’m pleased to announce that the next Monty Program-sponsored MariaDB Developer Meeting will be held in (or near) Athens, Greece. Update: See below for hotel/location information.

Monty Program tries to hold two MariaDB Developer Conferences / Monty Program company meetings each year. The most recent one was held in Portugal this past March and it’s past time for another one. Read more

MariaDB User Feedback

One thing which we, as developers of MariaDB, run into is that our personal database needs are not the same as many of our users. In fact, our needs are quite light compared to many. We have a MariaDB website, a company website, a knowledgebase, this blog, and that’s about it. None of them are particularly high traffic compared to what our customers have. But apart from talking to our customers, which are just a small percentage of the total MariaDB population, we wanted to have a way of finding out how MariaDB is used “in the real world”, so to speak.

Ornery Oneiric

I just updated to Ubuntu 11.10 “Oneiric” on one of my desktops and I ran into an issue with MariaDB.

It’s not an issue with MariaDB itself, more in how the MariaDB “Natty” .deb packages are configured. We haven’t released .deb packages for Ubuntu 11.10 “Oneiric”, but the Natty packages work fine, apart from this one configuration issue (and when we do release “Oneiric” packages, they will work out-of-the-box).

The main problem is that some things have moved around in “Oneiric” and Apparmor doesn’t like the MariaDB “Natty” Apparmor defaults file because it doesn’t account for some of the new destinations. Read more

MariaDB Crash Course

Ben Forta, the author of MySQL Crash Course and Sams Teach Yourself SQL in 10 Minutes, has written what I believe is the first MariaDB-specific book: MariaDB Crash Course. I just received word from Ben that the book is now shipping.

Most MySQL books can, of course, be used to learn almost everything you need to know about using MariaDB. But with all of the features and abilities MariaDB has gained in the MariaDB 5.2 and MariaDB 5.3 releases, it’s nice there is now a book specific to MariaDB. Read more

MariaDB now available as a hosted database via Jelastic cloud platform

About Jelastic:

Jelastic is the next generation of Java Platforms as a Service.

Unlike previous cloud platforms, Jelastic:

  • Can run any Java application and so does not require developers to change their code or get locked-into the platform,
  • Can scale any application up and down by automatically adding or removing memory and CPU units depending on the application load,
  • Takes all configuration and management worries away: developers simply specify the application stack and database options they need and Jelastic creates, configures, and maintains the environment for them
  • Supports a wide range of application server stacks including Tomcat, JBoss, Jetty, and GlassFish
  • Out of the box, allows users to get a preconfigured instance of MariaDB up and running and available to the application.

Progress Reporting in MariaDB 5.3

There are many new features in MariaDB 5.3. I’m looking forward to many of them, but one of the ones I’m most excited about is Progress Reporting.

It’s a fact of life in the database world that some commands take longer to run than others. Commands like ALTER TABLE, LOAD DATA INFILE, and adding and dropping an index simply take time to run, depending (of course) on your data and schema. I always have hated having to wait for those commands to run with no indication of how much progress has been made or how much is left to do. Read more

Looking for a Few Good Examples

In the #maria IRC channel the other day I fielded a question someone had about a DATETIME column where they wanted to SELECT by the year. The answer (which is probably obvious to many of you) is to use the YEAR() function like so:
select * from t1 where YEAR(d) = 2011;
(The above assumes the table is named “t1” and the DATETIME column is named “d”.)

In my reply I provided a link to the Date and Time Functions section of the AskMonty Knowledgebase, but when I looked at the entry for the YEAR() function, I noticed that the example given (which originated from the file scripts/fill_help_tables.sql which is found in the MySQL and MariaDB source) was not very helpful:

Newsletters from the MariaDB dev meeting in Lisbon

Every morning before any of the meetings get started I print out a small one page newsletter which contains (among other things) the program for the day. Rather than keep them private, Colin suggested I post them here. I call the newsletter the “MariaDB Programador de Journal” which (I think) translates to “MariaDB Programmer’s Journal” in Portuguese.

[Updated, 13 Mar 2011, to add the newsletter for that day.]

At the meeting we’ve also been taking notes and posting them online for what improvements we want to make this year in MariaDB to make it even better. Read more
