The answers given above match my understanding as well.
However, I agree that the following construction is somewhat strange:
```
RepartitionExec: partitioning=Hash([ip@0], 2), input_partitions=2
RepartitionExec: partitioning=RoundRobinBatch(2), input_partitions=1
```
It would actually be better in my mind if we could use the single operator
@YjyJeff suggestes
```
RepartitionExec: partitioning=Hash([ip@0], 2), input_partitions=2
```
However, as @yukkit says without changing how that operator works the
hashing would then be done a single record batch at a time.
