| ## Dataset Statistics |
|
|
| | Frequency | Series | Median series length | TsFile rows (observations) | Dynamic columns | Static columns | Data files | |
| |---|---:|---:|---:|---:|---:|---| |
| | 15T | 126 | 8,640 | 1,052,371 | 1 | 1 | `15T/15T_1..15T_2.tsfile` (2 shards) | |
| | 1H | 138 | 2,160 | 283,070 | 1 | 1 | `1H/1H.tsfile` | |
| | 5T | 118 | 25,920 | 2,960,408 | 1 | 1 | `5T/5T_1..5T_3.tsfile` (3 shards) | |
|
|
| ## Files |
|
|
| The Hugging Face dataset card YAML points `configs.data_files` to all `*.tsfile` files in this repository. |
|
|
| - `15T/15T_1.tsfile` |
| - `15T/15T_2.tsfile` |
| - `1H/1H.tsfile` |
| - `5T/5T_1.tsfile` |
| - `5T/5T_2.tsfile` |
| - `5T/5T_3.tsfile` |
|
|
| ## TsFile Storage Model |
|
|
| - Each original series (`id`) is stored as one TsFile device. |
| - Static covariate columns are stored as TAG columns: `subset`. |
| - Time-varying targets and dynamic covariates are stored as FIELD measurements. |
| - Source `timestamp` values are mapped to the TsFile `Time` column as millisecond timestamps. |
| - Table name(s): redset_15T, redset_1H, redset_5T. |
| |
| ### Column Schema |
| |
| | Column | Role | TsFile type | |
| |---|---|---| |
| | `Time` | Time column | INT64 | |
| | `id` | TAG (device dimension) | STRING | |
| | `subset` | TAG (device dimension) | STRING | |
| | `target` | FIELD (measurement) | FLOAT | |
| |
| ## Conversion Notes |
| |
| - The source FEV format stores each time series as one nested row containing `id`, `timestamp[]`, and target or covariate arrays. |
| - The TsFile conversion flattens those nested arrays into long rows. Therefore, the `TsFile rows` values above correspond to the number of timestamped observations after flattening. |
| - TAG columns identify the device and static metadata. FIELD columns contain values that change over time. |
| - Large logical tables may be split into multiple `.tsfile` shards such as `<name>_1.tsfile`, `<name>_2.tsfile`, and so on. Shards listed for the same frequency belong to the same logical table. |

| ## Reading Example |
| |
| ```python |
| from tsfile import TsFileReader |
| |
| reader = TsFileReader("15T/15T_1.tsfile") |
| schemas = reader.get_all_table_schemas() |
| # Table name(s): redset_15T, redset_1H, redset_5T |
| ``` |
