Amazon Redshift unterstützt die Verwendung von Python-UDFs nach dem 30. Juni 2026 nicht mehr. Wir werden damit beginnen, es schrittweise durchzusetzen. Weitere Informationen zum Ende der Lebensdauer von Python und zu den Migrationsoptionen finden Sie im [ Blogbeitrag](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/), der am 30. Juni 2025 veröffentlicht wurde. Die vorliegende Übersetzung wurde maschinell erstellt. Im Falle eines Konflikts oder eines Widerspruchs zwischen dieser übersetzten Fassung und der englischen Fassung (einschließlich infolge von Verzögerungen bei der Übersetzung) ist die englische Fassung maßgeblich. # Geofunktionen Beziehungen zwischen Geometrieobjekten basieren auf dem Dimensionally Extended Nine-Intersection Model (). DE-9IM Dieses Modell definiert Prädikate wie Equals, Contains und Covers. Weitere Informationen zur Definition von räumlichen Beziehungen finden Sie [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM)in Wikipedia. Weitere Informationen zur Verwendung raumbezogener Daten mit Amazon Redshift finden Sie unter [Abfrage von Geodaten in Amazon Redshift](geospatial-overview.md). Amazon Redshift bietet Geofunktionen für die Datentypen `GEOMETRY` und `GEOGRAPHY`. Im Folgenden sind die Funktionen aufgeführt, die den `GEOGRAPHY`-Datentyp unterstützen: + [ST\_Area](ST_Area-function.md) + [ST\_AsEWKT](ST_AsEWKT-function.md) + [ST\_ JSON
