> The distributed metadata log table can be simplified by leveraging the fact
> that replicas are all responsible for the entire token range. Given this
> assumption, we can then use {{ReversedLongLocalPartitioner}} introduced in
> CASSANDRA-19391 to make it much easier to append to/read from the tail of the
> log, effectively removing the need for the {{Period}} construct. This will
> also improve apply to the local metadata log used at startup.
