# 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.
