----------------------------------------
I am talking this over to get the fix into 2.0 release.
> GlobalStateManagerImpl should not write offsets of in-memory stores in
> checkpoint file

> Key: KAFKA-6711
> URL: https://issues.apache.org/jira/browse/KAFKA-6711
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 1.0.1
> Reporter: Cemalettin Koç
> Assignee: Cemalettin Koç
> Priority: Major
> Labels: newbie
>
> We are using an InMemoryStore along with GlobalKTable and I noticed that
> after each restart I am losing all my data. When I debug it,
> `/tmp/kafka-streams/category-client-1/global/.checkpoint` file contains
> offset for my GlobalKTable topic. I had checked GlobalStateManagerImpl
> implementation and noticed that it is not guarded for cases similar to mine.
> I am fairly new to Kafka land and probably there might be another way to fix
> issue.
