    A timestamp in 'YYYY-MM-DD hh:mm:ss[.fraction]' format that shows when the cloning operation started.

  • END_TIME

    A timestamp in 'YYYY-MM-DD hh:mm:ss[.fraction]' format that shows when the cloning operation finished. Reports NULL if the operation has not ended.

  • SOURCE

    The donor MySQL server address in 'HOST:PORT' format. The column displays 'LOCAL INSTANCE' for a local cloning operation.

  • DESTINATION

    The directory being cloned to.

  • ERROR_NO

    The error number reported for a failed cloning operation.

  • ERROR_MESSAGE

    The error message string for a failed cloning operation.

  • BINLOG_FILE

  • GTID_EXECUTED

    The GTID value for the last cloned transaction.

The clone_status table is read-only. DDL, including TRUNCATE TABLE, is not permitted.
