> 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.
