Transactional Application Protocol for Inconsistent Replication, or TAPIR, is a new protocol for linearizable distributed transactions built atop a new replication protocol that provides no consistency guarantees. TAPIR eliminates expensive coordination from the replication layer, yet provides the same transaction model and consistency semantics as existing transactional storage systems (e.g., Google's Spanner). It can commit transactions in a single round-trip, greatly improving both latency and throughput relative to existing systems.
