Writes can get lost if the primary dies and the secondary is promoted in the meanwhile.
- rubiquity 6y agoYes but this is dependent upon the specific replication protocol. Primary-Backup has this problem but Majority Quorums and Chain Replication do not.

- rubiquity 6y agoMy point is that Sequential Consistency isn’t a replication protocol, it’s a consistency model that you can have under various different replication protocols.
