---------------------------------------------------------------

The default TimeUUID(version 1).compareTo() doesn't compare Timestamp first 
then machine part, it compares MSB, then LSB

You could try {{TimeUUIDType.compare}}

{code}
UUID V1, Most Significant Bit:
0xFFFFFFFF00000000 time_low
0x00000000FFFF0000 time_mid
0x000000000000F000 version
0x0000000000000FFF time_hi
{code}

>             Project: Cassandra
>          Issue Type: Bug
>          Components: Local Write-Read Paths, Materialized Views
>            Reporter: Carl Yeksigian
>            Assignee: Kurt Greaves
>             Fix For: 4.x
>
>
> We only use the code path added in CASSANDRA-12268 for the view builder 
> because otherwise we would break the contract of the batchlog, where some 
> mutations may be written and pushed out before the whole batch log has been 
> saved.
> We would need to ensure that all of the updates make it to the batchlog 
> before allowing the batchlog manager to try to replay them, but also before 
> we start pushing out updates to the paired replicas.
