MySQL Error 3529: Component Load Failure
Description
This error indicates that MySQL attempted to load a component (such as a plugin, UDF, or service) but failed because the specified Uniform Resource Name (URN) was either invalid, malformed, or pointed to an inaccessible resource. It typically occurs during server startup, component installation, or when a component is explicitly loaded via SQL.
Error Message
Cannot load component from specified URN: '%s'.
Known Causes
4 known causesMalformed URN Syntax
The Uniform Resource Name (URN) specified for the component does not follow the correct format or contains typographical errors, preventing MySQL from locating or identifying the component.
Missing or Inaccessible Component
The actual component file (e.g., shared library, plugin file) referenced by the URN is either missing from the expected directory, has incorrect file permissions, or the MySQL server process lacks the necessary privileges to access it.
Improper Component Registration
The component was not correctly installed or registered with MySQL, or its configuration entry (e.g., in `my.cnf` or `mysql.component` table) points to a non-existent or outdated URN.
Component Version Incompatibility
The component being loaded is incompatible with the current MySQL server version, leading to a failure when the server attempts to initialize it.
