SeaweedFS is a highly scalable distributed storage system that provides S3‑compatible object storage, POSIX‑like file system access, and Iceberg table support. It stores billions of files with O(1) disk access and can scale horizontally by adding volume servers.

Use cases

• store billions of files with low‑latency access
• serve S3 objects on‑premise for Kubernetes workloads
• mount a POSIX‑compatible filesystem across a cluster via FUSE
• use SeaweedFS as the backend for Iceberg tables in analytics pipelines
• replace HDFS for big‑data storage with a simpler, faster system
• provide tiered storage with erasure‑coding for cost‑effective durability

When to choose

• You need on‑premise or self‑hosted object storage with S3 compatibility
• Your workload requires horizontal scaling to billions of files
• You want a unified system that supports both object and file‑system APIs
• You need built‑in erasure coding or tiered storage without external tools
• You run Kubernetes and want a CSI driver or operator for storage provisioning

When to avoid

• You prefer a fully managed cloud storage service with zero operational overhead
• Your data volume is small and does not justify managing a distributed cluster
• You require advanced features only available in the commercial Enterprise edition
• You need strict compliance certifications that are not covered by the open‑source version
