I have two questions: 1.
We plan to initially run Kafka without partitioning or replication, simply having two single node Kafka (broker) servers in two geographically diverse locations. Using periodic backups/snapshots across locations for disaster recovery. Our producer / consumer applications will process to/from each location. For such configurations, is it possible to run the Kafka broker without Zookeeper? If not, any plans for such a simplified configuration? We'd like to remove the extra app from the stack (Zookeeper) since it's not being utilized. 2. If we need to restore a Kafka node (simplified design above), I was hoping Kafka and Zookeeper could bootstrap itself as long as we can restore a copy of the /tmp/kafka-logs data. This dir contains the topics, log data, and high watermark. Unfortunately, it seems without the Zookeeper data, we cannot restore the node. Is there a way to restore a Kafka node if the Zookeeper data cannot be restored? What are the specific requirements to restore a Kafka broker from backups, if the /tmp/zookeeper must also be restored, are there any inconsistent state issues (i.e. backup of /tmp/kafka-logs and /tmp/zookeeper are not synchronized)? Thank you!
