Subject Is joined stream WindowedStream?
Date Tue, 25 Jul 2017 07:15:31 GMT
Hello Flink,



one question about join operator:

Flink Docu said "Join two data streams on a given key and a common
window",=  does "common window" mean that the joined stream is
windowedStream?

If it is normal datastream (not windowed), could the stream be windowed
aga= in with different window definition as the window specified by join?





Thank you and best regards

Wei
