OrangeFS: A Cloud‑Native Multi‑Protocol Distributed Data Lake Storage System

OrangeFS is Didi’s cloud‑native, multi‑protocol distributed data‑lake storage system that unifies POSIX, S3 and HDFS access on a single logical hierarchy, integrates with Kubernetes via a CSI plugin, supports on‑premise and public‑cloud backends, provides multi‑tenant isolation, and dramatically improves elasticity, utilization and latency for petabyte‑scale workloads such as ride‑hailing logs, machine‑learning training, finance and analytics.
