just a general question about the rocksdb in the Kafka stream, I see there is a folder at /tmp/kafka-stream/, which is used by the rocksdb in the kafka stream. so when a stream app get restarted, can the store data directly loaded from this folder? because I see there is very heavy traffic on the network to read from broker, assuming it's trying to rebuild the store. if so, what's the purpose of this rocksdb folder?
Thanks, Nan
