SwiftPaxos - Fast Geo-Replicated State Machines

Explore a cutting-edge conference talk on SwiftPaxos, a novel protocol for geo-replicated state machines presented at NSDI '24. Delve into the innovative approach that reduces latency in cloud services with replicated data across geographical regions. Learn how SwiftPaxos outperforms existing protocols by executing commands in just 2 message delays under low contention and 3 message delays otherwise. Discover the unique voting mechanism that allows replicas to vote twice, eliminating the need to restart the voting process during disagreements. Understand how this protocol achieves up to 2.9x better throughput compared to state-of-the-art alternatives. Gain insights into the challenges of maintaining high performance in distributed systems with varying levels of contention and how SwiftPaxos addresses these issues.
