> [~vrodionov] and [~rajeshbabu] were asking about this in RATIS-470. Can we
> improve the logic that reads through the "head" of the RaftLog to find the
> "LogService offset"?

> Josh, can we simplify this a little bit? Client gets Raft log ID one every
> append, for multi-get calls we can use this LogID (RAFT) as our start log ID
> to avoid iterating through all logs, then you can unwind log entries by using
> new logic, see above:
> int numRecordsInAppend = append.getDataCount();
> There is no need to iterate from the very beginning
