JuiceFS is a high-performance, POSIX-compatible distributed file system that stores file data in object storage (e.g., Amazon S3) and metadata in databases such as Redis, MySQL, TiKV, or PostgreSQL. It is designed for cloud-native environments, offering FUSE mounting, an S3 gateway, a Hadoop Java SDK, and a Kubernetes CSI driver.
Use cases
- mount s3 object storage as a local posix filesystem
- shared storage for kubernetes pods via csi driver
- replace hdfs for hadoop big data workloads
- shared file storage for machine learning training data
- store billions of files cheaply on object storage
- multi-cloud and hybrid cloud file storage
- s3-compatible gateway over a mounted filesystem
When to choose
- you need a fully POSIX-compatible shared filesystem backed by cheap object storage
- you want strong consistency across thousands of concurrent clients
- you run Kubernetes and need persistent shared volumes
- you want HDFS or S3 protocol compatibility without running a full storage cluster
- you need high metadata performance with Redis, TiKV, or a database as the metadata engine
When to avoid
- you need a single-node filesystem with no distributed requirements
- you cannot operate an external metadata engine like Redis or MySQL
- you need block storage or raw device access rather than file storage
- you require fully offline operation with no object storage backend
- you need a self-contained storage cluster like Ceph that manages its own disks
