Nezha: Deployable and High-Performance Consensus Using Synchronized Clocks [article]

Jinkun Geng and Anirudh Sivaraman and Balaji Prabhakar and Mendel Rosenblum
2022 arXiv   pre-print
This paper presents a high-performance consensus protocol, Nezha, designed for single-cloud-region environments, which can be deployed by cloud tenants without any support from their cloud provider.  ...  We also prototype two applications, a key-value store and a fair-access stock exchange, on top of Nezha to show that Nezha only modestly reduces their performance relative to an unreplicated system.  ...  (5) How does Nezha compare to Raft when both are equipped with log persistence to stable storage? (6) Does Nezha provide sufficient performance for replicated applications? Settings Testbed.  ...
