MySQL Clone Plugin – Installation, Usage, Progress Monitoring, Implementation Details, Limitations, and Comparison with XtraBackup

The MySQL Clone Plugin, added in 8.0.17, enables fast local or remote cloning of InnoDB data by installing the plugin, issuing CLONE commands, monitoring progress via performance_schema tables, and using the resulting GTID or binlog coordinates to build replicas, while observing limitations such as DDL restrictions and single‑instance operation, and offering advantages over XtraBackup through an extra page‑copy stage and simplified GTID handling.
