[jira] [Commented] (KAFKA-9031) Add possibility to reset Kafka streams application state to specific point in time

    [ https://issues.apache.org/jira/browse/KAFKA-9031?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16949800#comment-16949800 ] 

Levani Kokhreidze commented on KAFKA-9031:
------------------------------------------

Is a bit related to KAFKA-8236

Main difference is that in this ticket we're talking about consistent, periodic save-points no matter if new version of Kafka Streams application is deployed or not.

> Apache Flink has a feature called [savepoints|[https://ci.apache.org/projects/flink/flink-docs-stable/ops/state/savepoints.html]] which gives possibility to reset stream processing topology state to specific point in time. Similar feature can be useful for Kafka Streams applications as well.
