PS2, Line 15: So I added a flag FLAGS_ignore_delete_op_for_compact to solve 
this situation.
            : When we found a similar situation, we can schedule the compact 
algorithm to deal
            : with REDO deltas by set FLAGS_ignore_delete_op_for_compact to 
false. When we solve
            : this problem, we need to restore the flag to true to ensure that 
the compact
            : performance will not be affected.
> Do you mean we don't need this flag to keep this function on, just keep thi
Maybe add a flag such as FLAGS_check_delete_op_for_compact_ratio, it's ranged 
in [0,1], indicate how offen to check, the default value can be very low to 
reduce the affect on performance.
