### Is your feature request related to a problem or challenge? When concatenating (`||`) two `Utf8View`s, for every row we check two `Option`s and build the NULL bitmap incrementally. It would probably be faster to build the NULL bitmap in bulk, which would mean checking a single bitmap per row instead of examining both `Option`s. Annoyingly, `StringViewBuilder` doesn't have a way to use a precomputed null bitmap, so we still need to build the null bitmap itself incrementally. ### 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.
