Tuples - the data model in Storm
A tuple is the basic and constituent data structure in Storm. It's a named list of values that
starts its journey from the spout. It's then emitted from streams to bolts, then from bolts to
other bolts, where various stages of processing are executed. On successful completion of
all intended processing, as per the topology definition, the tuples are acked back to the
spout.
