-
{quote}Null Values in the Stream for a Left Join would indicate a Tombstone
Message
{quote}
This does not make sense to me. A KStream is an event/fact stream and thus
there are not delete/tombstone semantics. Only _changelogs_ have tombstone
semantics, but changelogs are modeled as `KTables` in Kafka Streams.
I still tend to agree that the current semantics are not ideal, but it's hard
to fix without introducing ambiguity (and the reason to drop them, is to avoid
ambiguity).
I guess a current workaround would be, to implement the join using a
`transform()` (or similar) – should not be too complicated.
