How It Works

Data Source: OpenWeatherMap API provides current weather conditions for each city every 5 minutes

Ingestion: Python script polls the API for 3 cities and writes measurements to Arc using MessagePack columnar format

Storage: Arc stores weather observations (temperature, humidity, pressure, conditions) in compressed Parquet files

Visualization: Multi-city charts showing temperature trends, humidity levels, and atmospheric pressure with automatic updates

  AVG(pressure) as avg_pressure,
  COUNT(*) as readings
FROM weather_tracking.weather_observations
WHERE time > NOW() - INTERVAL '24 hours'
GROUP BY city
ORDER BY city ASC
