Matthias J. Sax created KAFKA-6451: -------------------------------------- Summary: Simplify KStreamReduce Key: KAFKA-6451 URL: https://issues.apache.org/jira/browse/KAFKA-6451 Project: Kafka Issue Type: Bug Components: streams Affects Versions: 1.0.0 Reporter: Matthias J. Sax
If we do aggregations, we drop records with {{key=null}} or {{value=null}}. However, in {{KStreamReduce}} we only early exit if {{key=null}} and process {{value=null}} – even if we only update the state with it's old value and also only send the old value downstream (ie, we still compute the correct result), it's undesired and wasteful and we should early exit on {{value=null}}, too. This problem might occur for {{KStreamAggregate}} or other processors, too, and we need to double check those to make sure we implement consistent behavior. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
