## TsFile Storage Model
- Each original series (`id`) is stored as one TsFile device.
- Static covariate columns are stored as TAG columns: `type, Application_Usage, Infrastructure, Database, Networking, Security`.
- 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): boomlet_1062, boomlet_1209, boomlet_1225, boomlet_1230, boomlet_1282, boomlet_1487, boomlet_1631, boomlet_1676, boomlet_1855, boomlet_1975, boomlet_2187, boomlet_285, boomlet_619, boomlet_772, boomlet_963.

| `target_20` | FIELD (measurement) | FLOAT |
> Note: 15 original `id` values contained invalid identifier characters and were normalized to valid device names, for example 1062→_1062, 1209→_1209, 1225→_1225.
## 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("1062/1062.tsfile")
schemas = reader.get_all_table_schemas()
# Table name(s): boomlet_1062, boomlet_1209, boomlet_1225, boomlet_1230, boomlet_1282, boomlet_1487, boomlet_1631, boomlet_1676, boomlet_1855, boomlet_1975, boomlet_2187, boomlet_285, boomlet_619, boomlet_772, boomlet_963
