The Clone Plugin •The  clone_status  table provides the state of the current or last executed cloning operation. A clone operation has four possible states:  Not Started ,  In Progress ,  Completed , and  Failed . •The  clone_progress  table provides progress information for the current or last executed clone operation, by stage. The stages of a cloning operation include  DROP DATA ,  FILE COPY ,  PAGE_COPY , REDO_COPY ,  FILE_SYNC ,  RESTART , and  RECOVERY . 1. Connect to the recipient MySQL server instance. 2. Query the  clone_status  table: The  SELECT  and  EXECUTE  privileges on the Performance Schema is required to access the Performance Schema clone tables. To check the state of a cloning operation: mysql>  SELECT STATE FROM performance_schema.clone_status; +-----------+ | STATE | +-----------+ | Completed | +-----------+ mysql>  SELECT STATE, ERROR_NO, ERROR_MESSAGE FROM performance_schema.clone_status; +-----------+----------+---------------+ | STATE | ERROR_NO | ERROR_MESSAGE | +-----------+----------+---------------+ | Failed | xxx | "xxxxxxxxxxx" | +-----------+----------+---------------+ mysql>  SELECT STAGE, STATE, END_TIME FROM performance_schema.clone_progress; +-----------+-----------+----------------------------+ | stage | state | end_time | +-----------+-----------+----------------------------+ | DROP DATA | Completed | 2019-01-27 22:45:43.141261 | | FILE COPY | Completed | 2019-01-27 22:45:44.457572 | | PAGE COPY | Completed | 2019-01-27 22:45:44.577330 | | REDO COPY | Completed | 2019-01-27 22:45:44.679570 | | FILE SYNC | Completed | 2019-01-27 22:45:44.918547 | | RESTART | Completed | 2019-01-27 22:45:48.583565 | | RECOVERY | Completed | 2019-01-27 22:45:49.626595 | +-----------+-----------+----------------------------+ 1124 Monitoring Cloning Operations Using Performance Schema Stage Events For other clone status and progress data points that you can monitor, refer to Section 27.12.19, “Performance Schema Clone Tables” . A cloning operation may take some time to complete, depending on the amount of data and other factors related to data transfer. There are three stage events for monitoring the progress of a cloning operation. Each stage event reports  WORK_COMPLETED  and  WORK_ESTIMATED  values. Reported values are revised as the operation progresses. To review the details of each stage of a cloning operation: Should a failure occur during a cloning operation, you can query the  clone_status  table for error information: 2. Query the  clone_progress  table. For example, the following query provides state and end time data for each stage of the cloning operation: 1. Connect to the recipient MySQL server instance.
