Hi:
I am trying to understand broadcast functionality for DataStream and the
documentation indicates that it 'Broadcasts elements to every partition.'
My question is that since streams are unbounded:
1 What elements get broad to the partitions ?2. What happens as new elements
are added to the stream ? Are only the new elements broadcast ?3. Since the
broadcast operation returns a DataStream can it be used in join how do new (and
old) elements affect the join results ? 4. Similarly how does broadcast work
with connected streams ?
If there are some examples please let me know.
Thanks
Mans
