Get Big Amount of Attendance Data about zklibrary HOT 7 OPEN

It's better for you copy all attendance data to your local database before you send it to online database. After you finish copy all of them, you should clear attendance data on your device.
Next time, you should clear all attendance data after you send it to your database.

You can not do it. The only way to make it work faster, you must delete all attendance data after you copy it to your database.
