This Thursday (November 26th, 14:00 UTC), Giuseppe Maxia will present the Spider Storage Engine. This session was originally scheduled for October 15th but had to be postponed for technical reasons.

Here's from the abstract: Everybody needs sharding. Which is not easy to maintain. Being tied to the application layer, sharding is hard to export and to interact with. The Spider storage engine, a plugin for MySQL 5.1 and later, solves the problem in a transparent way. It is an extension of partitioning. Using this engine, the user can deal transparently with multiple backends in the server layer. This means that the data is accessible from any application without code changes. This lecture …

Recently we have released Workbench 5.2.4 Alpha. This version has some new features, and amongst them there is Workbench Administrator plugin or WBA plugin for short.

The plugin aims to ease the managing process of server instances. What we offer with WBA is a simple way to check status, configure and control one server instance. Some parts will resemble discontinued MySQL Administrator.

And here is a short summary of what we will have in WBA:

• Start/Stop server
• Edit server configuration (my.cnf)
• Manage user accounts
• Monitor user connections
• Status/Server variables browsing
• Log browsing
• Dump/Restore

In this alpha we have implemented a subset, which targets local usage only. Remote management and administration is upcoming. The subset includes:

• Add new Server Profiles
• Start/Stop the Server

It has been more than a year since my self-imposed hiatus from serious MySQL development started and I think it is about time that I get back into the saddle. I have a handful of working prototypes but I should get the code out there, back into the community.I learned a bunch of stuff during the past year at Google but in the end, working on JavaScript, HTML/CSS and Google proprietary languages

Over a chat on the #workbench IRC channel, Collin Cusce has written a handy little Lua script to automatically create relationships (through foreign keys) for his reverse engineered database.

Reverse engineering the DB to import tables into a diagram was easy, but their database used no “hard” foreign keys and an ER diagram without relationships wouldn’t be of much use. So one option would be to individually connect each foreign key column pair by hand, using the relationship picking tool . But doing that for the thirty-something tables in the database would be too much work and something could be overlooked and left out. The other option would be to automate that, since all such foreign keys followed a naming convention like <table>_id<column> or fk_id<table>. And that led to the following (slightly modified) …

A couple of  weeks ago I got an unhappy email from my web hosting provider telling me I was in violation of their Terms of Service. Of course I called them immediately and was told that there was a “phishing page” hidden in one of my web directories. My blog had been hacked, so I immediately started doing some house cleaning.

After the initial once over and deletion of any suspicious files I went looking for advice on how to “harden my installation”. Here’s what I found:

• Wordpress.org Codex Hardening Wordpress - Lots of good information here on hardening Wordpress including a general overview of Wordpress security considerations.
• …

I uploaded all of my past presentations to Slideshare recently, and realized that I hadn’t actually posted some of these on my blog in the past as well.

So I’ve created a new Presentations Page that has all of these together now.

It’s kind of funny to see the “MySQL for Oracle DBAs” presentation again - a lot has changed since 2006!

In any case, enjoy if you haven’t seen them - give them a look over if interested, and feel free to post comments or questions on the page!

I just applied the external stored procedure patch to a branch of MariaDB and uploaded it to LaunchPad.You can see the branch at https://code.launchpad.net/~atcurtis/maria/5.1-wl820Note that this is not in any reasonable condition to merge into MariaDB. Hopefully we can engage in dialog as to how we can bring this feature properly to MariaDB, MySQL and Drizzle, hopefully making the plugins

As many of you already know, MySQL Workbench offers powerful scripting support and a plugin interface that allows anybody to extend the application or add new functionality.

The latest addition to the WB plugin family has been written by Thomas Henlich. It features SQLite compatible SQL export of your Workbench models.

Download it from his blog and please provide feedback on the forums.

We are working on improving the scripting support in WB 5.2 and finally adding proper documentation so even more people can contribute.

It appears that LaunchPad.net is pretty slow.So that people can have something to play with, I have transferred files to my own web site.Presentation files:UC2009_presentation.zipSource downloads:mysql-5.1.34.tar.gzmysql-5.1.33.tar.gzPlease don't melt my router.... kthanx.
