Hi, I have an application which reads messages from a kafka queue, builds up a batch of messages, and then performs some action on that batch. So far I have just used the ConsumerGroup api. However, I realized there is a potential problem -- my app may die sometime in the middle of the batch, and then those messages could get completely lost. Kafka will think we've already read those messages, and so on restart it will skip to messages post batch.
1) Does the ConsumerGroup api have some way to allow you to control when the the position of the consumer-group is updated? I couldn't find anything relevant in ConsumerGroup, KafkaStream, or ConsumerIterator, but perhaps I overlooked something. 2) Do I need to switch to SimpleConsumer? It looks like that does not use zookeeper at all, I'd rather not have to manage all of the zookeeper stuff myself. This seems like a basic use case, so I'm probably missing something ... thanks, Imran (I'm using 0.8.0-beta1)
