Whoops, I should probably share my code as well! Here’s the topology: builder.stream(key_serde, val_serde, 'visit-update-events') .reduceByKey(-> (a, b) { a.merge b }, key_serde, val_serde, 'intermediate-visits') .to(key_serde, val_serde, 'visits’) This is using Ruby syntax, but hopefully it’s fairly readable. I’ve added it to this gist as well: https://gist.github.com/aviflax/3428cdbaa18aca9bf0a958c6d5eac2bd Thanks! Avi
