    +  Compaction help to improve query performance, because frequently load data, will generate
several CarbonData files, because data is sorted only within each load(per load per segment
and one B+ tree index).
    +  This means that there will be one index for each load and as number of data load increases,

the data from across the segments.
    +  
    +  There are two types of compaction Minor and Major compaction.
