> Thanks @Ted-Jiang -- the support for `IS NOT NULL` is also
quite neat.
@alamb sorry there is a bug here i will fix this it should
```
/// If set `with_not` to true: which means is not null
/// datafusion use false flag to prune unit (row group, page ..)
/// Given an expression reference to `expr`, if `expr` is a column
expression,
/// returns a pruning expression in terms of IsNotNull that will evaluate to
true
/// if the column may contain any nonnull values, and false if definitely
does not contain
/// nonnull values which any null values.
```
