> Out-of-order data will impact the aggregation query a lot. And users may do not care about discarding some out-of-order data.
> So we can add a configuration parameter (enable_discard_out_of_order_data) to allow iotdb to discard the out-of-order data (Compare with the partitionLatestFlushedTime in StorageGroupProcessor).
>  
> The default value is false.
