TsFile Schema

Conversion Notes

• —Each source .tsf data row is stored as one TsFile device.
• —Source .tsf attributes are stored as TAG columns.
• —The target series values are flattened into timestamped rows and stored as a FLOAT FIELD.
• —Time is synthesized from the source start timestamp and the .tsf frequency metadata, with millisecond precision.
• —Large outputs may be sharded by the TsFile conversion tool; all listed shards belong to the same logical table kaggle_web_traffic_weekly.
