Optimize split_part for scalar args #21204
Description
Is your feature request related to a problem or challenge?
SPLIT_PART(string, delimiter, position): delimiter and position are frequently scalars. We could take advantage of this to optimize split_part. At minimum we could use memchr::memmem::Finder to search for delimiters; maybe other optimization opportunities as well.
#21119 has some related discussion.
