Unless your in the desert under a rock (where rain is clearly needed), you will have heard of Drizzle - A Lightweight SQL Database for Cloud and Web. My company 42SQL is sponsoring the BuildBot for the Drizzle project. BuildBot is a system to automate the compile/test cycle required by most software projects to validate code changes.

Check out Installing Buildbot for what’s necessary to get a working installation. This is necessary for the Master and Slaves.

Configuration was a little more complicated then expected, due to lack of accurate documentation, and reading old docs at sourceforge. Be sure now to read …

Today I presented with Giuseppe Maxia of Sun Microsystems Inc at OSCON 08 on “MySQL Proxy: From Architecture to Implementation”. I was surprised to find that MySQL has a strong showing with a number of presentations this week.

Our talk covered the basics of MySQL Proxy, what’s coming in future features, and a number of examples of how I have used Proxy in consulting engagements to improve the information retrieval particularly for identifying performance problems.

This morning at OSCON 08, Tim O’Reilly’s opening keynote Open Source on the O’Reilly Radar included a slide on Drizzle, giving this new project maximum exposure to the Open Source community.

Drizzle was only officially announced yesterday in Drizzle, Clouds, “What If?” by primary architect Brian Aker. Things move fast. There has been a number of comments from people yesterday including Mark Attwood, Monty Widenus,Monty Taylor, …

Before today, Drizzle was known as a light form of rain found in Seattle (among other places). Not any more. If you have not read the news already today, Drizzle, Clouds, “What If?” is the new kid on the RDBMS bock.

Faster, leaner and designed with the original goals of ease-of-use, reliability and performance, Drizzle will make an impact in those organizations that are seeking a viable database storage solution for large scalable applications. The key to Drizzle is several fold. First, the crud has been removed. The first part of Drizzle development is to remove bloat or non functioning software from the MySQL tree. In fact if you monitor the commits, it reads like, this has been removed, these files have been deleted, this code has been refactored, this new library has been introduced. Design decisions that have limited MySQL’s development for years are being …

Ever since Sun Microsystems acquired MySQL, the most common question  that I had to answer  was "Is PostgreSQL dead at Sun?".  This question was not only raised from just PostgreSQL contributors but also other Sun Employees and  potential customers who may not even know that Sun actually sells PostgreSQL support services. 

This question will be further fueled with Josh Berkus's departure. (Josh, we will miss you.)  I admit from the period between the announcement of MySQL acquisition till recently, I too had my own doubts. But as Sun enters it new Fiscal Year FY09, and the clear directions from Management has given the right positive goals to the Sun PostgreSQL Team which will lead to Positive Growth, Self Sustaining model and …

Today I was doing some work on one of our database servers (each of them has 4 SAS disks in RAID10 on an Adaptec controller) and it required huge multi-thread I/O-bound read load. Basically it was a set of parallel full-scan reads from a 300Gb compressed innodb table (yes, we use innodb plugin). Looking at the iostat I saw pretty expected results: 90-100% disk utilization and lots of read operations per second. Then I decided to play around with linux I/O schedulers and try to increase disk subsystem throughput. Here are the results:

I will be speaking on July 29th in New York at an Entrepreneurs Forum on A Free Panel on Cloud Computing. With a number of experts including Hank Williams of KloudShare, Mike Nolet of AppNexus, and Hans Zaunere of New York PHP fame is should be a great event.

The focus of my presentation will be on “Extending existing applications to leverage the cloud” where I will be discussing both the advantages of the cloud, and the complexities and issues that you will encounter such as data management, data consistency, loss of control, security and latency for example.

Using traditional MySQL based applications I’ll be providing an approach that can lead to your application gaining greater power of cloud computing.
