Our current idea is to consume the last message, get the offset, and look backward from that offset to start a second subscription.  But then we saw the \"OffsetTail\" call in Consumer and said \"yipee!\"  But how does that call work?  it does not ask for a specific topic/partition, so how does it know what the current end of the partition is?"}}
