### 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. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
