OIL-041 — Synthetic Spare Parts Demand Dataset (Sample) (TsFile)

Apache TsFile version of xpertsystems/oil041-sample.

Overview

A schema-identical preview of OIL-041, the XpertSystems.ai synthetic spare-parts demand and inventory-optimization dataset for upstream, midstream, and downstream oil & gas operations. The full product covers ~6,000 facilities and ~450,000 parts across a 5-year horizon. This sample is the generator's sample mode (75 facilities × 1,500 parts × 45 warehouses × 365 days) covering all 13 product tables.

Conversion notes

• One TsFile per source CSV (13 tables); each table is stored as a single device, so the rig / well / tank / equipment / sensor identifiers stay ordinary FIELDs.
• Time = the table's own clock column as INT64 milliseconds (event timestamps, sample or inspection dates, and daily record dates). The clock columns used here are created_timestamp, event_timestamp, movement_timestamp, po_date, stockout_start.
• Tables with no clock column (facility_master, inventory_levels, reliability_labels, reorder_recommendations, spare_parts_master, supplier_lead_times, supplier_master, warehouse_master) use a synthetic row index over their stable source order as Time.
• No column is dropped. Rows that share a timestamp are ordered by a 1 ms step in stable source order, so daily tables keep their exact calendar day.

Usage

Read this dataset with the Java SDK. It is written with the zstd compressor. The Apache TsFile Java SDK reads every compressor, but the Python SDK (pip install tsfile) implements only UNCOMPRESSED, SNAPPY, GZIP and LZ4; opening this file with it yields no rows.

Read a converted file with the Apache TsFile Java SDK (org.apache.tsfile:tsfile):

String path = "emergency_orders.tsfile";
try (TsFileSequenceReader sequenceReader = new TsFileSequenceReader(path);
     TsFileReader reader = new TsFileReader(sequenceReader)) {
    // Devices are enumerated as IDeviceID objects. Tables with TAG columns
    // have multi-segment device ids that cannot be rebuilt from their string
    // form, so always use getAllDevices() rather than getAllDeviceIds().
    for (IDeviceID device : sequenceReader.getAllDevices()) {
        List<Path> paths = new ArrayList<>();
        for (MeasurementSchema schema : reader.getMeasurement(device)) {
