MariaDB Connector/C Plugins
MariaDB Connector/C supports loadable and built-in plugins across four categories: connection, pvio, I/O, and authentication, including remote_io and multiple auth methods.
MariaDB Connector/C functionality can be extended via loadable (or statically compiled in) plugins. As of the version 3.1.11 Connector/C comes with the following plugins
connection plugins
These plugins are used by the Connector/C to communicate with the MariaDB server.
These are plugins that are used whenever Connector/C needs to read a file.
For example, for LOAD DATA LOCAL INFILE statement, when a server requests the Connector/C to send a specific file.
This plugin uses libcurl to access remote files, it allows the client to execute statements like
LOAD DATA LOCAL INFILE 'http://mariadb.com/example.csv' INTO t1
Note that here, like with any LOAD DATA LOCAL, it'll be the client that fetches the file, not the server.
This plugin supports the following url schemes: http://, https://, ftp://, sftp://, ldap://, smb://.
These are authentication plugins. They are loaded automatically by the Connector/C when the server requests a specific authentication method.
mysql_native_password
This is a generic dialog plugin that asks the user a question (as instructed by the server) and sends the answer to the server. Everything is sent in plain text, one should enable SSL if secrets are sent via this plugin.
Graphical clients can customize the plugin to provide graphical dialog form. See
