             Summary: [C++] Implement concurrent IO read queue for file-like sources
                 Key: ARROW-500
                 URL: https://issues.apache.org/jira/browse/ARROW-500
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney


In a multithreaded setting, we may spawn many threads which will have access to a shared IO resources. It may be useful to create a thread-safe IO queue implementing the {{arrow::io::ReadableFileInterface}}, limiting the number of concurrent requests to the desired number (which may be 1, for services not permitting concurrent access).
