> State stores restoring from changelog topic not the source topic
> ----------------------------------------------------------------
>
> Key: KAFKA-7424
> URL: https://issues.apache.org/jira/browse/KAFKA-7424
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 1.1.1
> Reporter: James Hay
> Priority: Critical
>
> Hi,
>
> I've recently attempted to upgrade a streams application form 1.1 to 1.1.1
> and I noticed a drop in the number of messages being restored in our state
> stores.
> It appears that there is a change in 1.1.1 which causes our state stores to
> be restored from the changelog topic as opposed to version 1.1 where the
> stores are restored from the source topic. In our application this causes an
> issue as we switched to StreamsBuilder from KStreamBuilder in the middle of
> the applications lifetime and so the changelog doesn't represent a full
> history of the source topic.
> Has this switch been introduced intentionally? Is there a way to configure
> our application to use 1.1.1 and still use the source stream to restore state
> stores? Any recommendations on getting our changelog in sync with the source?
>
> Thanks
>
