   > What if two adding colums op running concurrently. e.g. op1 is running in heavy mode and we modify table to enable light schema change then op2 runs before op1 finishes.
   
   According to the compatibility matrix, op MODIFY_TABLE_PROPERTY will confict with op SCHEMA_CHANGE, so we can avoid this situation.
