CubeFS
| The CubeFS Project holds bi-weekly community online meeting. To join or watch previous meeting notes and recordings, please see meeting schedule and meeting minutes. |

Overview
CubeFS (储宝文件系统 in Chinese) is a cloud-native storage platform hosted by the Cloud Native Computing Foundation (CNCF) as a incubating project.
CubeFS has been commonly used as the underlying storage infrastructure for online applications, database or data processing services and machine learning jobs orchestrated by Kubernetes. An advantage of doing so is to separate storage from compute - one can scale up or down based on the workload and independent of the other, providing total flexibility in matching resources to the actual storage and compute capacity required at any given time.
Some key features of CubeFS include:
- Multiple Access Protocols Allowing users to access the same file over multiple protocols, such as POSIX/HDFS/S3
- Highly Scalable Metadata Service
Elasticity, scalability and strong consistency of metadata - Excellent Storage Performance
A lot of performance optimizations for large/small files and sequential/random writes - Multi-tenancy Support Provides an efficient mechanism to improve resource utilization and tenant isolation
- Hybrid Cloud Acceleration
Accelerate Hybrid Cloud IO performance through multi-level caching - Multiple Storage Engines
Provides a high-performance replication engine and a low-cost erasure coding engine
