K2: Reading quickly from storage across many datacenters
We present the K2 storage system that provides lower latency for large-scale and medium-scale web services using partial replication of data over many datacenters with strong guarantees: causal consistency, read-only transactions, and write-only transactions.

Tolerating slowdowns in replicated state machines using Copilots
Replicated state machines are linearizable, fault-tolerant groups of replicas that are coordinated using a consensus algorithm. Copilot replication is the first 1-slowdown-tolerant consensus protocol: it delivers normal latency despite the slowdown of any 1 replica.
