Overview

The collector keeps every capture, so the series extends back to when collection began.

Query contract

Preserve one canonical row per (event_time) before aggregating.

Analysis rules

  • Placeholders are NULL: filter valeurs_demandetotal IS NOT NULL, then argMax(valeurs_demandetotal, ingested_at) per event_time.
  • The collector re-reads HQ's whole local day every poll and keeps every capture (snapshot_at). Unpublished hours arrive as placeholders and are revised later: take argMax(value, ingested_at) per event_time AFTER dropping placeholders.

Interpretation

  • event_time is the UTC instant HQ stamps the value with. Québec civil time is America/Toronto.
  • Hydro-Québec licenses this data CC BY-NC 4.0: attribute Hydro-Québec when quoting it.
