| # rideshare (TsFile format)
|
|
|
| 156 hourly time series representations of attributes related to Uber and Lyft rideshare services for various locations in New York between 26/11/2018 and 18/12/2018.
|
|
|
| This repository contains the full source `.tsf` series from the Monash Time Series Forecasting Repository converted to [Apache TsFile](https://tsfile.apache.org/) format.
|
|
|
| ## Summary
|
|
|
| - Source dataset: [`Monash-University/monash_tsf`](https://huggingface.co/datasets/Monash-University/monash_tsf)
|
| - Original source: https://zenodo.org/record/5122114
|
| - Monash subset: `rideshare`
|
| - Modalities: Time-series
|
| - Source series: 2,304
|
| - Rows: 1,246,464 flattened timestamped observations
|
| - Frequency: `hourly`
|
| - Forecast horizon metadata: not specified
|
| - Missing-values metadata: True
|
| - Equal-length metadata: True
|
| - Missing target values preserved as NaN: 494,649
|
| - Series length range: 541 to 541
|
| - TsFile output: 2 files (rideshare_1.tsfile .. rideshare_2.tsfile)
|
|
|
| ## Files
|
|
|
| - `rideshare_1.tsfile`
|
| - `rideshare_2.tsfile`
|
|
|
| ## TsFile Schema
|
|
|
| | Column | Role | TsFile type |
|
| |---|---|---|
|
| | `Time` | TIME | INT64 |
|
| | `series_id` | TAG | STRING |
|
| | `series_name` | TAG | STRING |
|
| | `source_location` | TAG | STRING |
|
| | `provider_name` | TAG | STRING |
|
| | `provider_service` | TAG | STRING |
|
| | `type` | TAG | STRING |
|
| | `start_timestamp` | TAG | STRING |
|
| | `target` | FIELD | FLOAT |
|
|
|
| ## Conversion Notes
|
|
|
| - Each source `.tsf` data row is stored as one TsFile device.
|
| - Source `.tsf` attributes are stored as TAG columns.
|
| - The `target` series values are flattened into timestamped rows and stored as a FLOAT FIELD.
|
| - `Time` is synthesized from the source start timestamp and the `.tsf` frequency metadata, with millisecond precision.
|
| - Large outputs may be sharded by the TsFile conversion tool; all listed shards belong to the same logical table `rideshare`.
|
|
|
| ## Reading Example
|
|
|
| ```python
|
| from tsfile import TsFileReader
|
|
|
| reader = TsFileReader("rideshare_1.tsfile")
|
| schemas = reader.get_all_table_schemas()
|
| ```
