> The DataFrame API has a `collect` method which invokes the `collect(plan: Arc<dyn ExecutionPlan>) -> Result<Vec<RecordBatch>>` function which will collect records into a single vector of RecordBatches removing the partitioning via `MergeExec`.
> The DataFrame should also expose the `collect_partitioned` method so that partitions can be maintained.
> ```
> collect_partitioned(
>     plan: Arc<dyn ExecutionPlan>,
> ) -> Result<Vec<Vec<RecordBatch>>> 
> ```
