    topicAndPartition

    Topic and partition of which the offset is needed.

    earliestOrLatest

    A value to indicate earliest or latest offset.

    consumerId

    Id of the consumer which could be a consumer client, SimpleConsumerShell or a follower broker.

    returns

    Requested offset.
