Re: Initializing fetch offsets
David,

The API that you are looking for is OffsetRequest. If you pass in -2 as the
value for Time, it will get you the earliest offset available for that
partition. If you pass in -1, it will get you the latest offset.

You can find more information about the OffsetRequest and OffsetResponse
APIs here -
https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol#AGuideToTheKafkaProtocol-OffsetAPI

Please let us know if that description can be improved.

Thanks,
Neha
