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
