> 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 reduces  compact's performance.
