mysql5.1のプラグイン機構

英語は苦手なのでよく分からないのですが、MySQL5.1からプラグイン機構が取り入れられているらしい。
26.2. The MySQL Plugin Interface

MySQL 5.1 and up supports a plugin API that allows the loading and unloading of server components at runtime, without restarting the server. Currently, the plugin API supports creation of full-text parser plugins. Such a plugin can be used to replace or augment the built-in full-text parser. For example, a plugin can parse text into words using rules that differ from those used by the built-in parser. This can be useful if you need to parse text with characteristics different from those expected by the built-in parser.
