>
> To safely integrate with external prebuffer cache scenarios where memory is
> managed outside ORC, avoiding unnecessary reallocations and preventing
> ownership/lifecycle mismatches. Introduce the non-owning buffer support to
> DataBuffer so it can attach externally managed memory (via setData) without
> taking ownership of allocation/free.
