> Key: KAFKA-3497
> URL: https://issues.apache.org/jira/browse/KAFKA-3497
> Project: Kafka
> Issue Type: Sub-task
> Components: kafka streams
> Affects Versions: 0.10.0.1
> Reporter: Yuto Kawamura
> Assignee: Eno Thereska
> Fix For: 0.10.0.0
>
>
> Currently {{ProcessorContext}} only supports {{forward(K, V)}} which forwards
> KV to all children and {{forward(K, V, int childIndex)}} which forwards KV to
> specific children that is identified by an index of children List.
> While letting a Processor to issue messages which have arbitrary different
> downstream destination, it is not handy to keep ordering of calling
> {{addProcessor}}(or {{addSink}}) and childIndex consistent.
> Here I'd like to suggest introducing another signature {{forward(K, V, String
> childName)}} which allows to use child name(first argument to addProcessor or
> addSink) to indicate the destination downstream.
