NoSQL to MySQL with Memcached
(2011.04.11)by Mat Keep
The ever increasing performance demands of web-based services has generated significant interest in providing NoSQL access methods to MySQL - enabling users to maintain all of the advantages of their existing relational database infrastructure, while providing blazing fast performance for simple queries, using an API to complement regular SQL access to their data. The HandlerSocket development at DeNA is a great example of community innovation, with a solution implemented as a custom plug-in and protocol for the MySQL server daemon. We are hearing the community say they want NotOnly SQL - they want their trusted SQL RDBMS - plus, they want NoSQL techniques to access that data. So, we are previewing our NotOnlySQL solution for MySQL - delivered via memcached - with implementations to access both the InnoDB and MySQL Cluster (NDB) storage engines.

A deep look at MySQL 5.5 partitioning enhancements
(2009.12.24)by Giuseppe Maxia
The release of MySQL 5.5 has brought several enhancements. While most of the coverage went, understandably, to the semi-synchronous replication, the enhancements of partitioning were neglected, and sometimes there was some degree of misunderstanding on their true meaning. With this article, we want to explain these cool enhancements, especially the parts that were not fully understood.

(2009.05.15)by Rob Young
The MySQL Query Analyzer ("Quan") is designed to save development time on query coding and tuning by expanding on all of the good things found in the Slow Query Log, SHOW PROCESSLIST; EXPLAIN plan, and 5.1 profiler all with no dependence of any of these atomic things. To this end, we integrated Quan into the Enterprise Monitor so developers can monitor security, performance, availability AND all of their queries across all their MySQL servers from a single, consolidated view.
Why Move to MySQL from Microsoft SQL Server?
(2009.05.04)by Robin Schumacher
Before we get started, let me say that I always liked being a SQL Server DBA. My database experience started with DB2, then Teradata, followed by Oracle, and then SQL Server (and then a little bit of Sybase after that, followed by MySQL). Coming from the other databases, I found SQL Server the easiest and quickest to learn at the time, but of course, a lot of that had to do with the fact that Microsoft was really the only database vendor around then (I started with version 4.2 of SQL Server) that shipped any decent GUI management tools with their server. Take the tools away, and you basically had Sybase on Windows with the ISQL command line tool, which was not pretty by any means.
Developing Database Applications Using MySQL Connector/C++
(2009.04.15)by Giri Mandalika
The MySQL Connector/C++ provides an object-oriented application programming interface (API) and a database driver for connecting C++ applications to the MySQL Server. Connector/C++ implemented a significant percentage of the industry standard JDBC 4.0 specification in C++ world. This technical article shows the essential steps to build and install MySQL Connector/C++ driver, with simple examples to connect, insert, and retrieve data from a MySQL database. Application developers who are new to MySQL Connector/C++ but not to C++ programming and MySQL database, are the target audience.

Getting started with DTracing MySQL
(2009.03.05)by Amit Saha
DTrace is a dynamic tracing facility built into the Solaris and Open Solaris operating systems and can be used by system administrators and developers alike to observe the runtime behavior of user level programs and of the operating system itself. On one hand, DTrace can be used to identify potential bottlenecks in the running processes on a production system and on the other DTrace can help you understand the runtime behavior of an external program such as MySQL better.
Exception Error Handling Implementation in MySQL/VB.NET Windows Database Applications
(2009.02.10)by Ernest Bonat, Ph.D.
Error handling implementation in Windows database applications is a must for any Application Developer today. The main idea of error handling is to avoid application crashes by finding out the occurred errors and fixing them. Different programming languages have different ways of implementing error handling. Microsoft Visual Basic .NET (VB.NET) is the most common programming language for developing windows database applications today. VB.NET codes are provided in many websites, books and materials without error handling implementation. In this article I would like to introduce you to the basics of error handling implementation in MySQL/VB.NET windows database applications. I’ll be covering structured exception error handling, which was introduced for the first time in VB.NET 2002. I will also go over the latest technologies of disposing unmanaged recourses in .NET Framework with the Using statement. To write exception errors to a log text file, a generic procedure will be developed while MySQL data is loading, inserting, updating and deleting.
Another Look at MySQL 5.1’s SQL Diagnostic Tools
(2009.01.26)by Robin Schumacher
Prior to MySQL 5.1, it wasn’t all that easy to find the worst running SQL on a MySQL instance. And truth be told, MySQL still has a ways to go before it’s an effortless process. But, the good news is there are some new aids in MySQL 5.1 and MySQL Enterprise that do make it more efficient to find and troubleshoot bad SQL code that’s hiding inside a MySQL instance. Let’s take a quick tour through these new features and see what help they provide.
Allan Packer on performance tuning: Scaling MySQL
(2009.01.22)by Lenz Grimmer

Bound and Unbound DataGridView Control for MySQL 5.0/VB.NET 2008 Windows Applications
(2008.11.05)by Ernest Bonat, Ph.D.
Understanding and programming MySQL data load into the DataGridView control is a must for Windows Application Developers today. Many times, in real production environment the end-users need to see a result set of data to make daily business decisions. The main question is about how many records they need to see when the control gets loaded. The answer of the question is defined by the client's business rules. At this point application performance is a critical issue for Application Developers. In this paper I'll show you how load MySQL data into the DataGridView control using VB.NET bound and unbound programming modes. A timer class named Stopwatch for VB.NET will be used to measure the execution time between theses two programming modes.
Using Partitioning to Manage Satellite Networks
(2008.10.17)by Guy Adams, Chief Technical Officer at Parallel Ltd.
Our product historically used an Oracle backend, and after implementing simple date based range partitioning we got a 20-30 time performance increase in our queries. We had used MySQL in other more minor products we had developed, but we couldn’t move to it until partitioning was implemented. In Dec 05 we started to test MySQL partitioning, where partitioning syntax was supported but the optimizations were not in place. As soon as the optimizations were put in, we were able to run a side by side comparison against unpartitioned tables and Oracle partitions. Not only did we get in MySQL a 30+ times performance increase, but the MySQL version ran nearly twice as fast as the same Oracle configuration in a like for like test.
Advanced Bazaar for MySQL developers
(2008.09.16)by Guilhem Bichot
The MySQL project switched from Bitkeeper to another revision control system, Bazaar, in June 2008. My colleague Daniel Fischer wrote an excellent article describing how to get MySQL's code by using Bazaar, and how to compile a MySQL server binary from this. Here I am going to build on this knowledge and take it further, to show you how to modify MySQL's code for your needs, and share your modifications.
FC Inter Milan Using MySQL 5.1 Partitioning and Event Scheduler
(2008.09.10)by Corrado Pandiani
If you are a football (soccer) fan, then F.C. Internazionale may mean something to you. Or perhaps its more common name, Inter Milan sounds familiar? Next in our Use Case Competition articles, here's Corrado Pandiani's experience, about using MySQL to power inter.it, one of the most popular soccer sites in Europe. Not only that, but inter.it is using the latest MySQL 5.1 technology.
Using Partitioning and Event Scheduler to Prune Archive Tables
(2008.09.05)by Gregory J. Haase
First in our series of Use Case reports on new MySQL 5.1 features, we have Greg Haase of Lotame describing his innovative use of partitioning. Usually, the creators of new applications are unaware of the various tweaking that users may submit their features to, in order to achieve surprising results. We in the community team are usually on the tweaking side, and we like to surprise developers with (positive) side effects of the existing features. This time, we were caught by surprise. Greg's usage of partitioning and events is really cool!
Getting started with Bazaar for MySQL code
(2008.06.24)by Daniel Fischer
Since you're reading this, you probably know that Sun is switching to the Bazaar version control system for all development work on the MySQL server. Unlike the version control system that we've been using previously, Bazaar is an open source project and freely available to anyone. This means that it is now much easier to follow ongoing development, or even to participate in it! On the downside, just like our previous tool, Bazaar is not quite as straight-forward as traditional version control systems such as CVS or subversion. The aim of this article is to give an overview and a general idea of how to set up Bazaar, how to access the MySQL server source code repositories, and the basic commands for working with the source code.
MySQL Workbench for Database Change Management
(2008.05.08)by Robin Schumacher
Managing database change is an incredibly important discipline that very few database professionals overtly talk or worry about until they're in the thick of things with a particular database - moving it from development to production, making changes to a newly installed production database, or implementing an updated version of the database (new tables, modifications to existing objects, etc.) in a SaaS application. It's at that point where change management becomes very important because if you don't do things right the first time, you can make a royal mess of things and even (in a small number of cases) reach the point of no return where you've completely torched your database.
How the MySQL Enterprise Upgrade Advisor Helps DBAs Avoid Being Bitten by Known Bugs
(2008.04.01)by Rob Young
In an earlier article I described how MySQL Enterprise takes the guesswork out of deciding which version of the MySQL server customers should be running by providing alerts around regularly scheduled Monthly Rapid Update and Quarterly Service Pack releases of the Enterprise Server. Being of an old school "if it ain't broke don't fix it" mindset, I understand the conservative approach most DBAs take when deciding if a new release of any software is relevant to their environment. In fact, given the monthly frequency of Enterprise maintenance releases and the work involved with upgrading, I completely understand how recipients can begin to ignore Update Alerts (unless of course a known fix is on the way). Based on feedback from customers, MySQL colleagues, and my own field experience, I recognize that while notifications around the regular Enterprise Server drops is a good thing, upgrading an existing MySQL implementation is no small task and that a major part of removing guesswork around new releases involves helping those receiving notifications better understand how they are affected.
Why you want to be good at data modeling
(2008.03.27)by Robin Schumacher
To be really successful at working with databases, there are many different disciplines to become proficient in - things like disaster recovery, security management, data integration, and more. But there are less than a handful of things you want to be really good at; becoming super-skilled in them will help you enormously in your database career. And believe it or not, one of these key areas is data modeling and its kissing cousin, physical database design.
Reporting MySQL Internals with Information Schema plug-ins
(2008.02.21)by Roland Bouman
Last week, I described how to use the MySQL plug-in API to write a minimal 'Hello world!' information schema plug-in. The main purpose of that plug-in is to illustrate the bare essentials of the MySQL information schema plug-in interface.
MySQL Information Schema Plugins: the best kept secret of MySQL 5.1
(2008.02.12)by Roland Bouman
MySQL 5.1 offers an extremely useful feature called information_schema plugins. This feature allows dynamic runtime loading of a shared library into the MySQL server to implement a table in the information_schema database. The SQL standard (ISO/IEC 9075-11:2003) allows database implementations to extend the
information_schema. MySQL 5.1 transfers the possibility to do this directly to privileged database users so they can extend the information_schema themselves, in any way they see fit.
Enforcing Foreign Keys Programmatically in MySQL
(2006.07.10)by Philippe Campos
In this article we explore how to program foreign keys into a MySQL Server. This is important when your application requires referential integrity and the storage engine you’d like to use, as in the case of MyISAM or NDB (Cluster), does not support this functionality natively. We should note that InnoDB and the upcoming code-named “Falcon” storage engine, both support foreign keys.
