Hi all,is it possible to determine on client's side when consumer group's state become stable in group coordinator? From what I see (Kafka 0.9.0.1), when a consumer subscribes to a topic, it's not immediately ready to receive messages because of rebalancing process in the broker. So I'd like to know when my consumer is completely initialized and is able to receive messages. It would be especially helpful for integration tests with in-memory Kafka cluster.
