public interface PartitionIterator extends BasePartitionIterator<RowIterator>
An iterator over a number of (filtered) partition. PartitionIterator is to RowIterator what UnfilteredPartitionIterator is to UnfilteredRowIterator though unlike UnfilteredPartitionIterator, it is not guaranteed that the RowIterator returned are in partitioner order. The object returned by a call to next() is only guaranteed to be valid until the next call to hasNext() or next(). If a consumer wants to keep a reference on the returned objects for longer than the iteration, it must make a copy of it explicitely.
