In the gossip architecture, why does a replica manager need to keep both a ‘replica’ timestamp and
a ‘value’ timestamp?
What will be an ideal response?
The value timestamp reflects the operations that the replica manager has applied. Replica managers also need
to manage operations that they cannot yet apply. In particular, they need to assign identifiers to new operations,
and they need to keep track of which updates they have received in gossip messages, whether or not they have
applied them yet. The replica timestamp reflects updates that the replica manager has received, whether or not
it has applied them all yet.
