> Thanks @Ted-Jiang -- the support for `IS NOT NULL` is also quite neat.

/// 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.
