The NoSQL/relational database debate has been going on for quite some time. MariaDB, like MySQL is relational. And if you read these series of blog posts, you’ll realise that if you use MySQL correctly, you can achieve quite a lot.
OpenSQLCamp was a huge success! I took videos of most of the sessions (we only had 3 video cameras, and 4 rooms, and 2 sessions were not recorded). Unfortunately, I was busy doing administrative stuff for opensqlcamp for the opening keynote and first 15 minutes of the session organizing, and when I got to the planning board, it was already full….so I was not able to give a session.
OpenSQLCamp was a huge success! Not many folks have blogged about what they learned there….if you missed it, all is not lost. We did take videos of most of the sessions (we only had 3 video cameras, and 4 rooms, and 2 sessions were not recorded).
All the videos have been processed, and I am working on uploading
them to YouTube and filling in details for the video
descriptions. Not all the videos are up right now….right now all
the lightning talks are up.
Following on from our earlier announcement, Paul McCullagh has responded with the answers to your questions - as well as a few I gathered from other Percona folks, and attendees of OpenSQL Camp. Thank you Paul!
What’s the "ideal" use case for the PBXT engine, and how does it compare in performance? When would I use PBXT instead of a storage engine like MyISAM, InnoDB or XtraDB?
Unfortunately it is not possible to point to a specific category of applications and say, "PBXT will be better here, so try it". PBXT is a general purpose transactional storage engine, designed to perform well on a broad range of tasks, much like InnoDB. However, PBXT's log-based architecture makes performance characteristics different to both MyISAM and InnoDB/XtraDB. Tests show that PBXT's performance is similar to InnoDB but, depending on your database designed and the application, it can be faster.
PBXT is a …
[Read more]I forwarded on a list of questions about PBXT to Paul McCullagh today. While Paul's busy answering them, I'd like to announce that Robert Dempsey (InfiniDB storage engine) and Bradley C. Kuszmaul (TokuDB storage engine) have also accepted an interview. If you have any questions about either storage engine, please post them here by Friday 20th November.

[Read more]For the past two months, I have been running tests on TokuDB in my free time. TokuDB is a storage engine put out by Tokutek. TokuDB uses fractal tree indexes instead of B-tree indexes to improve performance, which is dramatically noticeable when dealing with large tables (over 100 million rows).
For those that like the information “above the fold”, here is a table with results from a test comparing InnoDB and TokuDB. All the steps are explained in the post below, if you want more details, but here’s the table:
| Action | InnoDB | TokuDB |
|---|---|---|
| Importing ~40 million rows | 119 min 20.596 sec | 69 min 1.982 sec |
| INSERTing again, ~80 million rows total | 5 hours 13 min 52.58 sec … |
Since I started doing the occasional consulting job for Open Query, I've seen a lot of MySQL servers that have been installed once and then forgotten about. This gave me the idea to do a short presentation about some basic MySQL server configuration. The first go was at DrupalCampMelbourne and I recently tried (and failed) to cram it into a three minute lightning talk slot at the LUV September meeting.
The title of the talk is (now) MySQL > YourSQL. I chose this not because I think that MySQL is better than the $other_database you use or because I may or may not run a newer version of MySQL on better hardware, but because I use InnoDB and …
[Read more]Mike Hogan, CEO of ScaleDB spoke at the Boston MySQL User Group in September 2009:
ScaleDB is a storage engine for MySQL that delivers shared-disk clustering. It has been described as the Oracle RAC of MySQL. Using ScaleDB, you can scale your cluster by simply adding nodes, without partitioning your data. Each node has full read/write capability, eliminating the need for slaves, while delivering cluster-level load balancing. ScaleDB is looking for additional beta testers, there is a sign up at http://www.scaledb.com.
Slides are online (and downloadable) at http://www.slideshare.net/Sheeri/scale-db-preso-for-boston-my-sql-meetup-92009

Recently Mark observed that we now all need a storage
engine independent test suite, Sun included! Well, as far as I
know, there is such a thing at Sun, sort of. Apparently it has
been used to test PBXT and other engines, but I've heard it is
not in good enough shape to be released.
But my question is, why not release it anyway? We could turn it
into an engine community project. I believe there are enough
engine developers out there to get this moving forward.
The secret is to start small, and just get a few tests to run
with all engines. Then additional tests can be added step by
step. Engines need a way to specify that they want to skip a test
entirely (e.g. transactional tests), and it should be easy to
customize results for various engines.
An example of a simple and elegant solution can be found in
Drizzle. As …
I was asked this question recently “I am wanting to create a simple MySQL database consisting of 5 tables”?
While it’s easy to tell people to RTFM, the question does warrant an answer for the MySQL beginner to provide a more specific guidance as to where to start, and what to do. As a expert in MySQL it’s easy to forget how you would describe what to do. Here are my tips to getting started.
Step 1. Download the MySQL 5.1 software for your platform (e.g. Linux, Windows, Mac etc) from MySQL 5.1 Downloads. There are many different versions of MySQL, MySQL 5.1 is the current production version.
Step 2. You will need to install the MySQL software. The MySQL reference manual is the place to go, Chapter 2 describes installing MySQL. You can also download a copy of the manual in …
