[jira] [Created] (ARROW-14008) [R][Compute] ExecPlan_run should return RecordBatchReader instead of Table

Ben Kietzman created ARROW-14008:
------------------------------------

             Summary: [R][Compute] ExecPlan_run should return RecordBatchReader instead of Table
                 Key: ARROW-14008
                 URL: https://issues.apache.org/jira/browse/ARROW-14008
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
            Reporter: Ben Kietzman


Wrapping a sink node's output as a RecordBatchReader is already supported in c++. Currently a table is returned in R's ExecPlan_run to skirt difficult lifetime considerations, but it'd be more correct to allow streaming batches out of an ExecPlan instead of doing all work before ExecPlan_run returns.
