----------------------------------------
[~guozhang] Should we move this to 2.2.0 as fixed version?
> 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
> Priority: Major
> Fix For: 2.1.0
>
>
> 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.
