[jira] [Resolved] (KAFKA-7393) Consider making suppression node
names independent of topologically numbered names.
[ https://issues.apache.org/jira/browse/KAFKA-7393?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
John Roesler resolved KAFKA-7393.
---------------------------------
Resolution: Won't Fix
We realized that Suppressed needs to support a name parameter in keeping with KIP-372, which provides a way to solve this problem. If you supply `withName` to Suppressed, it will be independent of topologically numbered names, as desired.

> Key: KAFKA-7393
> URL: https://issues.apache.org/jira/browse/KAFKA-7393
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: John Roesler
> Priority: Major
>
> See [https://github.com/apache/kafka/pull/5567#discussion_r214188984] (please keep the discussion on this Jira ticket).
> There is an opportunity to use a slightly different naming strategy for suppression nodes so that they can be moved around the topology without upsetting other nodes' names.
> The main downside is that it might be confusing to have a separate naming strategy for just this one kind of node.
> Then again, this could create important opportunities for topology-compatible optimizations.
>
> At a higher design/implementation cost, but a lower ongoing complexity, we could consider this naming approach for all node types.
