It seems like you're not explicitly controlling the offsets. Is that
correct?

If so, the moment you pull a message from the stream, the client framework
considers it processed. So if your app subsequently crashes before the
message is fully processed, and "auto-commit" updates the offsets in
Zookeeper, you will drop that message.

The solution to this to call commitOffsets() explicitly.
