Subject [jira] [Commented] (KAFKA-5836) Kafka Streams - API for specifying internal stream name on join
Date Sun, 08 Oct 2017 17:22:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-5836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16196241#comment-16196241
] 

Andy Chambers commented on KAFKA-5836:
--------------------------------------

We're using the confluent schema registry. It is my understanding that if you have schema
"a" at position "n" in the topology, and schema b at position "n+1", and then you add a node
into the topology before the one using schema "a", then KS will try to register a as a new
version of subject b.

> Automatic topic name can be problematic in case of streams operation change/migration.
> I'd like to be able to specify name of an internal topic so I can avoid creation of new
stream and data "loss" when changing the Stream building.
