Unique Key als Array Cloud-Formationsvorlage AWS

Question

Ich versuche, eine Cloud-Formationsvorlage für eine Dynamo-DB-Tabelle zu erstellen, die ich erstellen möchte. Ich möchte die folgenden Felder in der Tabelle: GUID, UniqueID, Service.

Wie kann ich die GUID und Service einen Primärschlüssel, der ein Array ist.

hier ist was ich

Answer 1

DynamoDB Partition oder Sortierschlüssel sollten skalaren Datentyp (d String, Zahl, Boolean usw.) sein. Die Dokumentdatentypen wie map, list, set können nicht Teil des Schlüsselattributs sein.
