Supported Storage Formats
Supported formats
Tunny Dashboard can read the following files directly — no conversion is needed.
| Format | Extension / Spec | Description |
|---|---|---|
| Optuna Journal file | .log |
An append-only operation log produced by Optuna's JournalStorage. |
| Optuna SQLite database | .db / .sqlite / .sqlite3 |
A file produced by Optuna's RDBStorage using SQLite. |
| Optuna RDB connection URL | — | Optuna's RDBStorage backends other than SQLite are read by URL, e.g. postgresql://user:pass@host:5432/db or mysql://user:pass@host:3306/db. |
| Flat trial CSV | *.csv |
One row per trial, in the DesignExplorer format output from tools such as Colibri and other external optimization tools. |
Practical notes
- Files are opened read-only, so you can safely inspect a database that belongs to an optimization still running elsewhere.
- Live Update (automatically refreshing while an optimization is in progress) is available only for Optuna Journal files.
