Storage
JuiceFS Shared Storage
Piglet Run uses JuiceFS to provide a distributed filesystem backed by PostgreSQL.
Why JuiceFS?
- POSIX Compatible: Works like a normal filesystem
- Database-Backed: Data stored in PostgreSQL
- Snapshots: Point-in-time recovery support
- Multi-User: Share workspace across sessions
