[jira] [Created] (ARROW-14266) [R] Use WriteNode to write queries

Neal Richardson created ARROW-14266:
---------------------------------------

             Summary: [R] Use WriteNode to write queries
                 Key: ARROW-14266
                 URL: https://issues.apache.org/jira/browse/ARROW-14266
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
            Reporter: Neal Richardson
             Fix For: 7.0.0


Following ARROW-13542. Any query that has a join or an aggregation currently has to first evaluate the query and hold it in memory before creating a Scanner to write it. We could improve that by using a WriteNode inside write_dataset() (and maybe that improves the other cases too, or at least allows us to delete some code).
