Earlier this year I had published a small blog about being efficient when using mysql prompt. This is a small continuation of it highlighting a couple of other cool features which I really find very useful when working command line (i.e. always!). The first I’m gonna list here is setting the prompt itself by typing –

With thanks to Patrick Galbraith and his DBD::drizzle 0.200 I am now able to test client benchmarks side by side with MySQL and Drizzle.

For simple benchmarking with clients, generally when I have little time, I use a simple Perl framework mybench. I was able to change just the connection string and run tests.

The diff of my two scripts where:

---
> my $user      = $opt{u} || "appuser";
> my $pass      = $opt{p} || "password";
> my $port      = $opt{P} || 3306;
> my $dsn       = "DBI:mysql:$db:$host;port=$port";
---
< my $user      = $opt{u} || "root";
< my $pass      = $opt{p} || "";
< my $port      = $opt{P} || 4427;
< my $dsn       = "DBI:drizzle:$db:$host;port=$port";
---

It’s too early to tell what improvement Drizzle will make. Just running my …

I've now posted all the current talk submissions to the OpenSQL Camp Wiki. A big Thank You to everyone who contributed so far and helped us to bang the drum for this event! If you haven't heard about OpenSQL Camp yet, it's a subconference of the Free and Open Source Conference (FrOSCon) in St. Augustin, Germany, which takes place on August 22+23. The topic of OpenSQL Camp is "Open Source databases and related technologies" and we're looking for interesting presentations in this field.

As we have 12 session slots to fill, we still have room for at least 6 more submissions! It's also a tad bit MySQL-centric at the moment, that should definitely change! We would love to get some more diversity to cover a broader range of Open Source Database technology.

So please submit your talk proposals and help …

This Thursday (July 2nd, 13:00 UTC), Roland Bouman will will take the Sakila sample database and explain how to design and load a data warehouse for it, and how to use that to create those reports and charts that make managers smile. Along the way, he'll explain often uttered terms and concepts such as dimensional model, denormalization, star schema, OLAP, data staging, business intelligence, ETL and data integration. Roland's session is titled Starring Sakila - A Data Warehouse Mini-Tutorial.

There is a very simple test to show MySQL replication in action and to also better understand the basics of MySQL Replication. With a configured MySQL environment we can run the following test on your MySQL master, and monitor the MySQL slave.

If you would like to try this, you can use MySQL SandBox which can launch a MySQL Master/Slave configuration in seconds. You can get started with MySQL Sandbox and Download 3.0.04.

Sandbox setup

$ make_replication_sandbox ~/mysql/mysql-5.1.35-osx10.5-x86.tar.gz
$ cd ~/sandboxes/rsandbox_5_1_35/

On the master

We will use a modified version of the numbers procedure found at …

Introduction

StackOverflow is an amazing site for coding questions. It was created by Joel Spolsky of joelonsoftware.com, Jeff Atwood of codinghorror.com, and some other incredibly smart guys who truly care about user experience. I have been a total fan of SO since it went mainstream and it's now a borderline addiction (you can see my StackOverflow badge on the right sidebar).

Update 6/21/09: This server is currently under very heavy load (10-200), even with caching plugins enabled. Please bear with me as I try to resolve the situation.
