Seattle Safety Data

Seattle 911 Fire Dispatch E911 SFD Mobile Public Safety

911-meldingen voor de brandweer van Seattle.

Volume en retentie

Deze gegevensset wordt opgeslagen in de Parquet-indeling. De dataset wordt dagelijks bijgewerkt en bevat sinds 2019 in totaal ongeveer 800.000 rijen (20 MB).

Deze gegevensset bevat historische records die vanaf 2010 tot heden zijn verzameld. U kunt in onze SDK gebruikmaken van parameterinstellingen om gegevens op te halen binnen een specifiek tijdsbereik.

Opslaglocatie

Deze gegevensset wordt opgeslagen in de Azure-regio US - oost. Het wordt aanbevolen om rekenresources in US - oost toe te wijzen voor affiniteit.
