We are just evaluating Kafka starting with the latest v0.9.0.1. A very
basic use case is to start initial consumers to begin from the earliest
entry only for the first time, the second restarts will start from an
offset wherever they left off. From what I read, you can set
auto.offset.reset = earliest to do this, but it does not seem to work.
consumer.subscribe(Collections.singletonList(KafkaProperties.topic));
ConsumerRecords<Integer, String> records = consumer.poll(1000);
for (ConsumerRecord<Integer, String> record : records) {
System.out.printf("offset = %d, key = %s, value = %s",
record.offset(), record.key(), record.value());
}
