[jira] [Created] (ARROW-12688) [R] Use DuckDB to query an Arrow Dataset

Neal Richardson created ARROW-12688:
---------------------------------------

             Summary: [R] Use DuckDB to query an Arrow Dataset
                 Key: ARROW-12688
                 URL: https://issues.apache.org/jira/browse/ARROW-12688
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++, R
            Reporter: Neal Richardson


DuckDB can read data from an Arrow C-interface stream. Once we can provide that struct from R, presumably DuckDB could query on that stream. 

A first step is just connecting the pieces. A second step would be to handle parts of the DuckDB query and push down filtering/projection to Arrow.
