IMPORTANT:
This article is out of date and the replication API has been updated. Please see the follow-up article for the most up to date information! OK, so here is the next installment in the Drizzle replication article series. Today, I'll be talking about the flow of the Command message object through the CommandReplicator and CommandApplier APIs. If you missed the first article about the structure of the Command message and Google Protobuffers, you may want to read that first. We'll only be talking in this article about what happens on one server. We will be discussing the Command Log in the next article, and then discuss how messages are passed from one …

As you probably have experienced yet MySQL does not always provide all internal information as you might want to have them and as you are used to have from other RDBMS.

MySQL plans to improve this implementing the/a performance schema and its probably already partly done in MySQL 5.4. But who knows when this will be finished and what it contains at all...

What is not provided to me I want to gather myself... But how? Other RDBMS provide interfaces to attach applications directly to their memory to retreive information. But MySQL does not. So I was looking for a way to read an other process memory.

I have no clue about programming and thus changing MySQL code was out of focus. Further I am looking for a solution you can use immediately on a running systems at consulting gigs. Some tries to read /proc/<pid>/mem with a little php script failed.

An article by Domas M. helped me. I do not have to write …

2. SQL Pie Chart -- an ASCII pie chart, drawn by SQL code. Horrifying and yet inspiring. Compare to PostgreSQL code to produce ASCII Mandelbrot set. (via jdub on Twitter and Simon Willison)

Changes (as compared to 8.12) include:

Features:
* SQLyog can be started with a ‘-dir’ switch like “SQLyogENT -dir somefolder”. This -dir switch specifies where SQLyog will look for the sqlyog.ini file and where all writable files will be saved. This was mainly implemented for users that want to have all SQLyog-related files on a removable drive or some kind of encrypted storage. Note that if you use the setting in ‘preferences’ to store TAGS file some specific place the ‘preferences’ setting will still have effect, also if the -dir switch is used.
* Improved/rearranged the GRIDS in Data Sync and Import External Data wizards.
* SJA mail functionality now supports SSL/TLS encryption. This applies to SJA for Linux and SJA for Windows running on Windows, but not  SJA for Windows running on Wine, as we did not find any way to access encryption functionality from Wine. …

TOTD #93 showed how to get started with Java EE 6 using NetBeans 6.8 M1 and GlassFish v3 by building a simple Servlet 3.0 + JPA 2.0 web application. JPA 2.0 + Eclipselink was used for the database connectivity and Servlet 3.0 was used for displaying the results to the user. The sample demonstrated how the two technologies can be mixed to create a simple web application. But Servlets are meant for server-side processing rather than displaying the results to end user. JavaServer Faces 2 (another new specification in Java EE 6) is designed to fulfill that purpose.

After reading Fernando Ipar’s interesting post on partial indexes for string columns, there were two things I wanted to note:

First, this trick works quite well, but only if your like clauses only ever use the wildcard on the right hand side (or not at all). MySQL will not be able to use the index if the like contains a wildcard on the left.

Consider the following table definition:

mysql> show create table people\G
*************************** 1. row ***************************
Table: people
Create Table: CREATE TABLE `people` (
`person_id` int(15) NOT NULL default '0',
`username` varchar(255) default NULL,
`email` varchar(255) default NULL,
PRIMARY KEY (`person_id`),
KEY `people_username` (`username`(5))
) ENGINE=MyISAM DEFAULT CHARSET=latin1
1 row …
