Ensure the scanner callback waits for all the UIDs to resolve before calling scan to retrieve the next set of results. Not waiting would cause the scanner to close prematurely and return incomplete results.

Ensure the scanner callback waits for all the UIDs to resolve before calling scan to retrieve the next set of results. If we clear lookups between each row, we only ensure the lookups have resolved for the last row in the iterator.
Not waiting can cause the scanner to close prematurely and return incomplete results.
