> If we get a REDO delta with full of delete op, wich means there is no update 
> op in the file. The current compact algorithm will not schedule the file do 
> compact. If such files exist, after accumulating for a period of time, it 
> will greatly affect our scan speed. However, processing such files every time 
> compact reducesĀ  compact's performance.
