### Is your feature request related to a problem or challenge? There seem some opportunities for optimizing `ArrowBytesViewMap` using some more cleverness. For e.g. ClickBench query 5, >50% CPU is spent during `intern`: <img width="1728" height="125" alt="Image" src="https://github.com/user-attachments/assets/18b07fd2-a39f-4a29-884e-6562e20b1985"; /> A lot of it relates to getting / comparing the bytes from the buffers, etc (append_value, get_value, memcmp, etc.). ``` <img width="1366" height="181" alt="Image" src="https://github.com/user-attachments/assets/4a84138e-97e8-49d6-8df1-7b6fae0811c6"; /> ``` ### Describe the solution you'd like We should be able to avoid (re)creating views every time and comparing against slices, by storing/comparing the views directly, and avoiding the overhead of the `GenericByteViewBuilder` methods. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
