   Figure 1. Clear data

   • All Data: runs the FLUSHALL command to clear all data of the instance. Cleared data cannot be restored.

   • Expired Data: runs the SCAN command to batch clear all expired data of the instance. Cleared data cannot be restored. You can select Upgrade Now or Update During Maintenance.

   Warning

   Data clearing takes effect immediately and cleared data cannot be restored. This may affect your business. Proceed with caution. We recommend that you back up the data of your Tair instance before you clear data. For more information, see Automatic or manual backup.
