MySQL 8.4 Release Notes
Previously, MySQL enabled masking and de-identification capabilities using a server-side plugin, but transitioned to use the component infrastructure as an alternative implementation. The following table briefly compares MySQL Enterprise Data Masking and De-Identification components and the plugin library to provide an overview of their differences. It may assist you in making the transition from the plugin to components.
Note
Only the data-masking components or the plugin should be enabled at a time. Enabling both components and the plugin is unsupported and results may not be as anticipated.
