Summary: Relax non-null key requirement for stream-globalTable joins Key: KAFKA-10277 URL: https://issues.apache.org/jira/browse/KAFKA-10277 Project: Kafka Issue Type: Improvement Components: streams Reporter: Matthias J. Sax In general, Kafka Streams requires that key and value are non-null for aggregations and join input records. While this requirement is reasonable in general, for stream-globalKTable joins it's questionable for the stream input record key. The join is based on a `keySelector` and it seems to be sufficient to require that the `keySelector` returns a not-null join-key for the stream record. We should consider to relax the non-null key requirement for stream-side input records. -- This message was sent by Atlassian Jira (v8.3.4#803005)
