GpuColumnarBatchIterator

abstract class GpuColumnarBatchIterator extends Iterator[ColumnarBatch] with AutoCloseable

An abstract columnar batch iterator that gives options for auto closing when the associated task completes. Also provides idempotent close semantics.

This iterator follows the semantics of GPU RDD columnar batch iterators too in that if a batch is returned by next it is the responsibility of the receiver to close it.

Generally it is good practice if hasNext would return false than any outstanding resources should be closed so waiting for an explicit close is not needed.
