Strong and Efficient Consistency with Consistency-Aware Durability

Explore a groundbreaking approach to durability in distributed storage systems through this award-winning conference talk from FAST '20. Delve into consistency-aware durability (CAD), a novel technique that enables strong consistency without sacrificing performance. Learn about cross-client monotonic reads, a powerful consistency property for leader-based systems that ensures monotonic reads across failures and sessions. Discover ORCA, a modified version of ZooKeeper that implements CAD and cross-client monotonic reads, and examine its impressive performance improvements over both weakly and strongly consistent ZooKeeper implementations. Gain insights into how this innovative approach can significantly enhance throughput and reduce latency in distributed storage systems, particularly in geo-distributed settings.
