Getting Started
Configuration
Data backends, metadata backends, and mount options.
Data backends
| Backend | Flag | Notes |
|---|---|---|
| LocalFS | --data-backend local-fs | Object blocks as files on a local directory |
| S3-compatible | --data-backend s3 | MinIO, RustFS, Ceph RGW, AWS S3, … |
Metadata backends
| Backend | Flag | Notes |
|---|---|---|
| SQLx (SQLite / PostgreSQL / MySQL) | --meta-backend sqlx | Single-file SQLite is the simplest start |
| Redis | --meta-backend redis | Low-latency metadata operations |
| etcd | --meta-backend etcd | Strongly consistent clustered metadata |
| TiKV | --meta-backend tikv | Horizontally scalable transactional metadata |
Mount options
All mount options are published as part of benchmark configurations — see Reproducibility.
Performance tuning
The complete cache, S3, FUSE, writeback, and metadata cache recipes are documented in Performance tuning parameters. Start with the safe baseline there before applying a workload-specific profile.
