Instant InnoDB

Overview of this book

<p>InnoDB, the default storage engine for MySQL, is one of the most robust and commonly used in the world today. It can, however, be initially daunting to learn how to start implementing its features, and it can pose unique problems to the beginner user. This guide is written to address these problems.</p> <p>"Instant InnoDB" addresses everything you need to know for the installation, configuration, load testing, analysis, and long term support of an InnoDB based database environment. If you've ever wanted to learn more about InnoDB but didn't want to sit down with a formidably large or dry read, then the Instant InnoDB&nbsp; is your ideal companion.</p> <p>"Instant InnoDB" guides you expertly through the initial setup and system requirements for getting up and running with a simple environment that can be used for the development and testing of the InnoDB engine.<br /><br />After an in-depth look at basic and advanced configuration settings we delve into the internals of InnoDB that allow it to handle Multi-Version Concurrency Control and ACID transaction compliance. We will then dig deeper into advanced topics, such as memory buffer tuning methods and transaction log file handling. We'll then cover typical approaches and solutions to monitoring the database and reporting on operational states.</p> <p>By the end of the Instant InnoDB , we will have covered the common approaches to troubleshooting and error handling, as well as providing you with solutions to the most common architectural, administrative, and engineering related situations that arise when working with the InnoDB database engine.</p>

Troubleshooting InnoDB performance


In many cases we can point to hardware resources as the bottlenecks of database performance issues, and the solution in those cases is to upgrade hardware to increase available CPU cycles, add more RAM for memory buffers, or faster disk systems for increased IOPS workloads. Query optimization is another common task for improving performance and should be addressed in conjunction with hardware and InnoDB tuning.

However, performance bottlenecks can arise from different issues when using InnoDB and are not always hardware or query related. Incorrect configuration values for your application's workload or failing to change the default InnoDB settings on a server are common causes of poor InnoDB performance.

The following are baseline variables that can be changed from their default values to help prevent performance bottlenecks. These variables should also be inspected if you encounter performance issues, as they are primary methods for altering resource utilization...
