| ## Dataset Statistics
|
|
|
| | Frequency | Series | Median series length | TsFile rows (observations) | Dynamic columns | Static columns | Data files |
|
| |---|---:|---:|---:|---:|---:|---|
|
| | 1D | 1,115 | 942 | 7,352,310 | 7 | 10 | `1D/1D_1..1D_2.tsfile` (2 shards) |
|
| | 1W | 1,115 | 133 | 889,770 | 6 | 10 | `1W/1W.tsfile` |
|
|
|
| ## Files
|
|
|
| The Hugging Face dataset card YAML points `configs.data_files` to all `*.tsfile` files in this repository.
|
|
|
| - `1D/1D_1.tsfile`
|
| - `1D/1D_2.tsfile`
|
| - `1W/1W.tsfile`
|
|
|
| ## TsFile Storage Model
|
|
|
| - Each original series (`id`) is stored as one TsFile device.
|
| - Static covariate columns are stored as TAG columns: `Store, StoreType, Assortment, CompetitionDistance, CompetitionOpenSinceMonth, CompetitionOpenSinceYear, Promo2, Promo2SinceWeek, Promo2SinceYear, PromoInterval`.
|
| - 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): rossmann_1D, rossmann_1W.
|
|
|
| ### Column Schema
|
|
|
| | Column | Role | TsFile type |
|
| |---|---|---|
|
| | `Time` | Time column | INT64 |
|
| | `id` | TAG (device dimension) | STRING |
|
| | `Store` | TAG (device dimension) | DOUBLE |
|
| | `StoreType` | TAG (device dimension) | STRING |
|
| | `Assortment` | TAG (device dimension) | STRING |
|
| | `CompetitionDistance` | TAG (device dimension) | DOUBLE |
|
| | `CompetitionOpenSinceMonth` | TAG (device dimension) | DOUBLE |
|
| | `CompetitionOpenSinceYear` | TAG (device dimension) | DOUBLE |
|
| | `Promo2` | TAG (device dimension) | DOUBLE |
|
| | `Promo2SinceWeek` | TAG (device dimension) | DOUBLE |
|
| | `Promo2SinceYear` | TAG (device dimension) | DOUBLE |
|
| | `PromoInterval` | TAG (device dimension) | STRING |
|
| | `DayOfWeek` | FIELD (measurement) | FLOAT |
|
| | `Sales` | FIELD (measurement) | FLOAT |
|
| | `Customers` | FIELD (measurement) | FLOAT |
|
| | `Open` | FIELD (measurement) | FLOAT |
|
| | `Promo` | FIELD (measurement) | FLOAT |
|
| | `StateHoliday` | FIELD (measurement) | STRING |
|
| | `SchoolHoliday` | FIELD (measurement) | FLOAT |
|
|
|
| > Note: 2230 original `id` values contained invalid identifier characters and were normalized to valid device names, for example 1→_1, 2→_2, 3→_3.
|
|
|
| ## 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("1D/1D_1.tsfile")
|
| schemas = reader.get_all_table_schemas()
|
| # Table name(s): rossmann_1D, rossmann_1W
|
| ```
