ett2 (TsFile)

Apache TsFile version of the ett2 subset of GIFT-Eval.

Overview

GIFT-Eval is a benchmark for general time-series forecasting, covering 23 datasets (≈144,000 series and 177M data points) across seven domains, ten frequencies, and a range of forecast horizons. This repository contains a single subset of that benchmark.

ett2 — Electricity Transformer Temperature, station 2 (ETT) load and oil-temperature series.

The .tsfile files are organized by the original GIFT-Eval frequency under data/:

• data/15T/: 1 .tsfile files
• data/D/: 1 .tsfile files
• data/H/: 1 .tsfile files
• data/W/: 1 .tsfile files

Schema (TsFile structure)

• Time (INT64, milliseconds) — the timestamp of each observation.
• Each series is stored as a TsFile device; per-series identifiers from GIFT-Eval are carried as TAG columns, and the observed values are FIELD columns.

Usage

Read the .tsfile files with the Apache TsFile Java or Python SDK.
