Since batch processing can be considered as *a special case of stream
processing*, we recommend implementing
a streaming pipeline first as it is the most general implementation for both
bounded and unbounded data.
+
+In theory, a streaming pipeline can execute all operators. However, in
practice, some operations might
+not make much sense as they would lead to ever-growing state and are therefore
not supported. A global
+sort would be an example that is only available in batch mode. Simply put: it
should be possible to
+run a working streaming pipeline in batch and but not necessarily vice versa.
