class GpuKeyBatchingIterator extends Iterator[ColumnarBatch] with Arm

Given a stream of data that is sorted by a set of keys, split the data so each batch output contains all of the keys for a given key set. This tries to get the batch sizes close to the target size. It assumes that the input batches will already be close to that size and does not try to split them too much further.
