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 …

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 …

The OmniMySQL project is now officially known as OmniSQL (for obvious potential legal reasons). I find myself using this tool more and more, so I thought it was about time to add some new features. The new project download site is now http://code.google.com/p/omnisql/. Let me know of any bugs and/or enhancements! CHANGELOG: 0.0.5 - [...]
Until recently, I was a student employee at the Oregon State University Open Source Lab. My career there ended, like many, with that painful process known as graduation. I got invaluable experience at the lab, not the least of which being the knowledge gained as their main (only) database administrator. One of my great pleasures in that position, was learning how to configure MySQL replication and manage clusters of replicating database servers. Even the simple case of a single master and a single slave has its edge cases.
