| # Exchange Rate (TsFile)
|
|
|
| Apache TsFile version of the `exchange_rate` long-term-forecasting subset of
|
| [`thuml/Time-Series-Library`](https://huggingface.co/datasets/thuml/Time-Series-Library).
|
|
|
| ## Overview
|
|
|
| Daily exchange rates of eight countries.
|
|
|
| - **Rows:** 7,588 time steps.
|
| - **Channels:** 8 numeric variables.
|
| - A single multivariate series; no TAG/device dimension.
|
|
|
| ## Schema (TsFile structure)
|
|
|
| - **Time** (INT64, milliseconds) — parsed from the source `date` column.
|
| - **FIELD** (8 columns, FLOAT) — the measured channels. Channel names are
|
| made schema-safe (e.g. `%`→`pct`, spaces→`_`, leading digits prefixed `c_`).
|
|
|
| The source `date` string is dropped (losslessly encoded into Time). No rows or
|
| numeric columns are dropped.
|
|
|
| ## Usage
|
|
|
| Read the `.tsfile` files with the Apache TsFile Java or Python SDK.
