-------------------------------------

             Summary: Checkpoint of InMemoryStore along with GlobalKTable 
                 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


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.
