State machine replication (SMR) uses Paxos to enforce the same
inputs for a program (e.g., Redis) replicated on a number of hosts,
tolerating various types of failures. Unfortunately, traditional Paxos
protocols incur prohibitive performance overhead on server programs
due to their high consensus latency on TCP/IP. Worse, the
consensus latency of extant Paxos protocols increases drastically
when more concurrent client connections or hosts are added. This
paper presents APUS, the first RDMA-based Paxos protocol that
aims to be fast and scalable to client connections and hosts. APUS
intercepts inbound socket calls of an unmodified server program,
assigns a total order for all input requests, and uses fast RDMA
primitives to replicate these requests concurrently.
We evaluated APUS on nine widely-used server programs (e.g.,
Redis and MySQL). APUS incurred a mean overhead of 4.3% in
response time and 4.2% in throughput. We integrated APUS with an
SMR system Calvin. Our Calvin-APUS integration was 8.2X faster
than the extant Calvin-ZooKeeper integration. The consensus
latency of APUS outperformed an RDMA-based consensus protocol
by 4.9X. APUS source code and raw results are released on github.
