### Describe the enhancement requested The scalar string predicate/measurement kernels return NotImplemented for string_view / binary_view input, so evaluating a string predicate on a view array requires casting the whole column to utf8/binary first. This adds view support to the kernels that read a string and emit a fixed-width type (no string output): - match_substring(_regex), match_like, starts_with, ends_with - find_substring(_regex), count_substring(_regex) - binary_length, utf8_length - string_is_ascii, ascii_is_*, utf8_is_* Kernels that emit strings/lists (utf8_upper/lower/trim*, replace_substring, split_pattern, etc.) are out of scope for a follow-up. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
