A Multi-Leader Protocol with Auto-Balanced Leadership via Sharded Keyspace (Shipyard & Skiff)

Authors: Xincheng Yang, Kyle Hale

Description: This work introduces an auto-balanced leadership protocol via sharding, achieving higher throughput than EPaxos (SOSP '13 & NSDI '21) by reducing communication message complexity. I independently developed the core idea, implemented the protocol, and conducted experiments, while my advisor provided expert guidance and feedback throughout the project and manuscript preparation. This work has been accepted at IPDPS (2026).

A Cross-Shard Consistency Model at Globe Scale (CoPPar Tree)

Authors: Xincheng Yang, Kyle Hale

Description: This work introduces a data structure that addresses consistency in cross-sharded systems, achieving higher throughput than ZooNet (ATC '16) through a history composition mechanism. I carried out the core research(conceptual design, implementation, experiments, and drafting writing), with my advisor providing expert guidance and feedback throughout the process. This work was presented as a poster at GCASR (2023) and published at ISPDC (2025)
