   > There is no clear path to storing BooleanArray as BitMap vs Buffer, which would allow removing offset
   
   In arrow2, the value buffer of Boolean Array is stored as `BitMap`, because lots of bitwise operations are related to this type. 
   In arrow-rs currently, as bitwise operations are related to `Buffer` but not `BitMap`, I guess `Buffer` is a better type for BooleanArray.
