> 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.
