-----------------------------------

             Summary: [C++] Add Copy virtual method to arrow::Buffer
                 Key: ARROW-1360
                 URL: https://issues.apache.org/jira/browse/ARROW-1360
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney


Some kinds of buffers (like GPU buffers) may need to use something other than 
{{memcpy}} (or its parallel variant) to copy memory. It might be useful to 
provide an abstract API for copying between RAM and some buffer.
