The problem with Kafka is that we never know when a consumer is "truly" inactive.
But - if you decide to define inactive as consumer who's last offset is lower than anything available on the log (or perhaps lagging by over X messages?), its fairly easy to write a script to detect and clean them directly on ZK. BTW. Why do you need to clean them? What issue do you see with just letting them hang around?
