Upsert-Entitäten
Die Upsert-Operation kombiniert die Aktionen des Aktualisierens und Einfügens von Daten. Milvus bestimmt, ob eine Aktualisierung oder eine Einfügeoperation durchgeführt werden soll, indem es prüft, ob der Primärschlüssel existiert. In diesem Abschnitt wird erläutert, wie eine Entität eingefügt werden kann und wie sich die Upsert-Operation in verschiedenen Szenarien verhält.
Übersicht
Wenn Sie eine Entität in einer Sammlung aktualisieren müssen oder nicht sicher sind, ob Sie sie aktualisieren oder einfügen sollen, können Sie die Operation "Upsert" verwenden. Bei der Verwendung dieses Vorgangs muss unbedingt sichergestellt werden, dass die in der Upsert-Anforderung enthaltene Entität den Primärschlüssel enthält; andernfalls wird ein Fehler auftreten. Beim Empfang einer Upsert-Anfrage führt Milvus den folgenden Prozess aus.
Prüfen Sie, ob das Primärfeld der Sammlung AutoId aktiviert hat.
a. Ist dies der Fall, ersetzt Milvus den Primärschlüssel in der Entität durch einen automatisch generierten Primärschlüssel und fügt die Daten ein.
b. Wenn nicht, wird Milvus den Primärschlüssel der Entität verwenden, um die Daten einzufügen.
Führen Sie einen Löschvorgang auf der Grundlage des Primärschlüsselwerts der Entität durch, die in der Upsert-Anforderung enthalten ist.
Upsert Entitäten
Upsert Entität in einer Sammlung
In diesem Abschnitt werden Sie Entitäten in eine Sammlung einfügen, die mit der Schnellstartmethode erstellt wurde. Eine auf diese Weise erstellte Sammlung hat nur zwei Felder, nämlich id und vector. Außerdem ist in dieser Sammlung das dynamische Feld aktiviert, sodass die Entitäten im Beispielcode ein Feld namens color enthalten, das nicht im Schema definiert ist.
