             Summary: [C++] Implement zero-copy Slice method on arrow::Buffer that retains reference to parent
                 Key: ARROW-317
                 URL: https://issues.apache.org/jira/browse/ARROW-317
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney


This will help prevent referenced memory from being garbage-collected while it is referenced by other buffers (for example, in an IPC setting, where we construct Arrow vectors/arrays without copying the input memory).

Closely related to this: resizeable buffers that are referenced by other buffers should return error status when calling {{Resize}} (if possible).
