   > Not sure about other type but for StringView, I can only think of 
iterating all the filtered row and `append_value` one by one. If there is no 
further optimization we can do, I think we can implement the append logic in 
datafusion
   
   Does approach seems like that for filter?
   - loop the `input array` and `input predicate`
   - get the value of needed row(`true` in `input predicate`), and 
`append_value` to the builder
