The Information Schema PLUGINS table contains information about server plugins.
It contains the following columns:
PLUGIN_NAME
Name of the plugin.
PLUGIN_VERSION
Version from the plugin's general type descriptor.
PLUGIN_STATUS
Plugin status, one of ACTIVE, INACTIVE, DISABLED or DELETED.
PLUGIN_TYPE
Plugin type; STORAGE ENGINE, INFORMATION_SCHEMA, AUTHENTICATION, REPLICATION, DAEMON or AUDIT.
PLUGIN_TYPE_VERSION
Version from the plugin's type-specific descriptor.
PLUGIN_LIBRARY
Plugin's shared object file name, located in the directory specified by the system variable, and used by the and statements. NULL if the plugin is complied in and cannot be uninstalled.
PLUGIN_LIBRARY_VERSION
Version from the plugin's API interface.
PLUGIN_AUTHOR
Author of the plugin.
PLUGIN_DESCRIPTION
Description.
PLUGIN_LICENSE
Plugin's licence.
LOAD_OPTION
How the plugin was loaded; one of OFF, ON, FORCE or FORCE_PLUS_PERMANENT. See .
PLUGIN_MATURITY
Plugin's maturity level; one of Unknown, Experimental, Alpha, Beta,'Gamma, and Stable.
PLUGIN_AUTH_VERSION
Plugin's version as determined by the plugin author. An example would be '0.99 beta 1'.
It provides a superset of the information shown by the SHOW PLUGINS statement. For specific information about storage engines (a particular type of plugins), see the information_schema.ENGINES table and the SHOW ENGINES statement.
This table provides a subset of the Information Schema information_schema.ALL_PLUGINS table, which contains all available plugins, installed or not.
The table is not a standard Information Schema table, and is a MariaDB extension.
The easiest way to get basic information on plugins is with SHOW PLUGINS:
