Guozhang Wang created KAFKA-6443: ------------------------------------ Summary: KTable involved in multiple joins could result in duplicate results Key: KAFKA-6443 URL: https://issues.apache.org/jira/browse/KAFKA-6443 Project: Kafka Issue Type: Bug Components: streams Reporter: Guozhang Wang
Consider the following multi table-table joins: {code} table1.join(table2).join(table2); // "join" could be replaced with "leftJoin" and "outerJoin" {code} where {{table2}} is involved multiple times in this multi-way joins. In this case, when a new record from the source topic of {{table2}} is being processing, it will send to two children down in the topology and hence may resulting in duplicated join results depending on the join types. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
