a DStream for the batch-by-batch concatenation of this and other. Note we fill both PDStreams with empty batches. This implies both PDStreams are implicitly treated as they where infinitely extended with empty batches
(Changed in version 2.9.0) The behavior of scanRight
has changed. The previous behavior can be reproduced with scanRight.reverse.
true iff each batch of this dstream is contained in the batch at the same position in other. Note this implies that true can be returned for cases when other has more batches than this
(Changed in version 2.9.0) transpose
throws an IllegalArgumentException
if collections are not uniformly sized.
An object of this class represents a finite prefix of a discrete data streams, aka prefix DStream or just PDStream
