[jira] [Commented] (KAFKA-6535) Set default retention ms for Streams repartition topics to infinity

["Matthias J. Sax (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-6535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16353244#comment-16353244 ] 

Matthias J. Sax commented on KAFKA-6535:
----------------------------------------

Meta comment: sometimes, people need to manually repartition via `through()` – should we allow users to do the same thing for this case? I mean, setting retention to infinite and tell Kafka Streams to purge data for those topics?

> After KIP-220 / KIP-204, repartition topics in Streams are transient, so it is better to set its default retention to infinity to allow any records be pushed to it with old timestamps (think: bootstrapping, re-processing) and just rely on the purging API to keeping its storage small.
