Flowmatic Smart City Dataset

Flowmatic smart-city dataset with hourly UTC CSV partitions. 1 hour file(s), 143 total row(s). Files live under data/hourly/ and are indexed in data/hourly/manifest.json.

Pipeline run: cmqhlxrr708tno42sajnwwxf6
Updated: 2026-06-17T05:05:27.655Z
Partition scheme: hourly-utc
Manifest: data/hourly/manifest.json

Hourly CSV layout

Rows are grouped by eventTime into one CSV per UTC hour:

  • Directory: data/hourly/
  • File pattern: YYYY-MM-DDTHH.csv (example: data/hourly/2026-05-21T14.csv)
  • Append exports merge only within the touched hour file(s), not the whole dataset.
Hour (UTC) File Rows Updated
