    @jackylk I have doubt about the below scenario:
    For sort_columns, the minmax is ordered for all the blocks/blocklets in one 
segment.
    
    Suppose that we are doing filtering on sort_columns and the filter looks 
like Col1='bb'.
    If the minmax values for blocklet#1, blocklet#2, blocklet#3 is [a,c), 
[c,d), [d,e).
    After carbondata find max value of blocklet#1 already covers filter value 
'bb', Will it **still compare** filter value 'bb' with the minmax of the rest 
blocklets#2/#3?
    
    I though the BTree can be used to avoid these comparison. Am I wrong?
