                 Key: ARROW-10019
                 URL: https://issues.apache.org/jira/browse/ARROW-10019

substring returns a substring of a StringArray starting at a given index, and with a given optional length.

{{fn substring(array: &Array, start: i32, length: &Option<u32>) -> Result<ArrayRef>}}

This operation is common in strings, and it is useful for string-based transformations
