Subject [jira] [Created] (KAFKA-3839) Handling null keys in KTable.groupBy
Date Tue, 14 Jun 2016 22:01:30 GMT
Guozhang Wang created KAFKA-3839:

             Summary: Handling null keys in KTable.groupBy
                 Key: KAFKA-3839
                 URL: https://issues.apache.org/jira/browse/KAFKA-3839
             Project: Kafka
          Issue Type: Bug
          Components: streams
            Reporter: Guozhang Wang

This is first reported by [~jeff.klukas@gmail.com].

Similarly as we handle null keys in KStream join and aggregations in KAFKA-3561 (https://github.com/apache/kafka/pull/1472),
for KTable.groupBy operators we should also gracefully handle null keys by filter them out
since they will not be participating in the aggregation.
