> This issue adds a functionality to efficiently compute the hash code for a
> consecutive memory region. This functionality is important in practical
> scenarios because it helps:
> * Avoid unnecessary memory copy.
> * Avoid repeated conversions between Java objects & Arrow buffers.
> Since the algorithm for calculating hash code has significant performance
> implications, we need to design an interface so that different algorithms can
> be easily introduces as plug-ins.
