Book Description

MySQL has introduced a Plugin API with its latest version – a robust, powerful, and easy way of extending the server functionality with loadable modules on the fly. But until now anyone wishing to develop a plugin would almost certainly need to dig into the MySQL source code and search the Web for missing bits of the information.This is the first book on the MySQL Plugin API. Written together with one of the Plugin API primary architects, it contains all the details you need to build a plugin. It shows what a plugin should contain and how to compile, install, and package it. Every chapter illustrates the material with thoroughly explained source code examples.Starting from the basic features, common to all plugin types, and the structure of the plugin framework, this book will guide you through the different plugin types, from simple examples to advanced ones. Server monitoring, full-text search in JPEG comments, typo-tolerant searches, getting the list of all user variables, system usage statistics, or a complete storage engine with indexes – these and other plugins are developed in different chapters of this book, demonstrating the power and versatility of the MySQL Plugin API and explaining the intricate details of MySQL Plugin programming.

What you will learn

• Build and install a plugin, and learn how to package it for distributing separately from MySQL
• Add new functions to MySQL using the UDF interface
• Declare new MySQL status and configuration variables from a plugin, and use Daemon plugins for a simple push style server monitoring

• Use fulltext parser plugins to tolerate user errors, and search for text in binary data formats, for example, JPEG, or text that is stored outside the database
• Store and retrieve rows and convert your custom data format to what MySQL understands using the storage engine plugin
• Create a parser that indexes comments from JPEG files using the libexif library
• Understand how the indexing API works, and how to work around the incompatibilities between your indexing engine and MySQL expectations
• Learn about new features of the Plugin API, available beyond MySQL 5.1
