Fixed unexpected behavior of streams-table join in StreamsJoin example #9

Closed pmeister closed 2 years ago

pmeister commented 3 years ago

The leftJoin of the combinedStream to the usersTable was failing to join any records from the usersTable because they had later timestamps than the corresponding stream records. The fix is to modify the TopicLoader to create the users first so that they have the earliest timestamps.
