ecgbench (TsFile)
Apache TsFile version of deepsynthbody/ECGBench.
Overview
- Tables: 1 TsFile table(s), 21,799 rows in total.
ecgbench: 21,799 rows, 1984-11-09 09:17:34 鈫?2001-06-11 16:43:01 (UTC)
Schema (TsFile structure)
ecgbench.tsfile
- Time (INT64, milliseconds) 鈥?the source
recording_datecolumn. - TAG:
device鈥?device dimension; query one device withWHERE device=.... - FIELD (26):
filename_100(string),filename_500(string),ecg_id(int64),patient_id(double),age(double),sex(int64),height(double),weight(double),nurse(double),site(double),report(string),scp_codes(string),heart_axis(string),infarction_stadium1(string),infarction_stadium2(string),validated_by(double),second_opinion(int64),initial_autogenerated_report(int64),validated_by_human(int64),baseline_drift(string),static_noise(string),burst_noise(string),electrodes_problems(string),extra_beats(string),pacemaker(string),strat_fold(int64)
Conversion notes
- One TsFile per source table (1 tables). Tables whose source carries several entities per file are stored as one device per entity, using
deviceas the TAG. - Time = the table's own clock column as INT64 milliseconds. The clock columns used here are
recording_date. - No column is dropped. Rows that share a timestamp inside one device are ordered by a 1 ms step in stable source order, so calendar columns keep their exact day.
Usage
Read this dataset with the Java SDK. It is written with the
zstdcompressor. The Apache TsFile Java SDK reads every compressor, but the Python SDK (pip install tsfile) implements onlyUNCOMPRESSED,SNAPPY,GZIPandLZ4; opening this file with it yields no rows.
Read a converted file with the Apache TsFile Java SDK (org.apache.tsfile:tsfile):
import org.apache.tsfile.file.metadata.IDeviceID;
import org.apache.tsfile.read.TsFileReader;
import org.apache.tsfile.read.TsFileSequenceReader;
import org.apache.tsfile.read.common.Path;
import org.apache.tsfile.read.expression.QueryExpression;
import org.apache.tsfile.read.query.dataset.QueryDataSet;
import org.apache.tsfile.write.schema.MeasurementSchema;
import java.util.ArrayList;
import java.util.List;
String path = "ecgbench.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)) {
String name = schema.getMeasurementName();
if (name != null && !name.isEmpty() && !name.equalsIgnoreCase("Time")) {
paths.add(new Path(device, name, true));
}
}
QueryDataSet dataSet = reader.query(QueryExpression.create(paths, null));
while (dataSet.hasNext()) {
System.out.println(dataSet.next());
}
}
