> 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.
