Hi, Stream one has one element. Stream two has 20000 elements.
Both streams derive from side-outputs. I am using the DataStream API in batch execution mode. I want to join them on a common key and window. I am certain the keys match, but the flat join does not seem to be working. I deduce that their windows are not matching. How can I debug which window they were assigned to? Also, how can I name or UID a joined stream? Any advice would be appreciated. Thank you.
