Citron: Distributed Range Lock Management with One-sided RDMA

Jian Gao, Youyou Lu, Minhui Xie, Qing Wang, and Jiwu Shu, Tsinghua University

Range lock enables concurrent accesses to disjoint parts of a shared storage. However, existing range lock managers rely on centralized CPU resources to process lock requests, which results in server-side CPU bottleneck and suboptimal performance when placed in a distributed scenario.

We propose Citron, an RDMA-enabled distributed range lock manager that bypasses server-side CPUs by using only one-sided RDMA …
