> {{Currentlly, minor compaction only consider the num of segments and major}}
> compaction only consider the SUM size of segments, but consider a scenario
>  that the user want to use minor compaction by the num of segments but he
>  dont want to merge the segment whose datasize larger the threshold for
>  example 2GB, as it is no need to merge so much big segment and it is time
>  costly.
>  so we need to add a parameter to control the threshold of segment included
>  in minor compaction, so that the user can specify the segment not included
>  in minor compaction once the datasize exeed the threshold, of course default
>  value must be threre.
