Eliminare uno schema per i dati strutturati

Puoi eliminare uno schema solo se tutti i documenti associati sono stati eliminati. In caso contrario, il tentativo non andrà a buon fine. Dopo aver eliminato uno schema, puoi chiamare il metodo schemas.create per crearne uno nuovo.

Per eliminare uno schema per i dati strutturati:

REST

1. Trova l'ID datastore. Se hai già l'ID del tuo datastore, vai al passaggio successivo.

   1. Nella Google Cloud console, vai alla pagina AI Applications e nel menu di navigazione, fai clic su Datastore.

      Vai alla pagina Datastore

   2. Fai clic sul nome del tuo datastore.

   3. Nella pagina Dati del datastore, recupera l'ID datastore.

2. Elimina lo schema.

   curl -X DELETE \
   -H "Authorization: Bearer $(gcloud auth print-access-token)" \
   -H "Content-Type: application/json" \
   "https://discoveryengine.googleapis.com/v1beta/projects/PROJECT_ID/locations/global/collections/default_collection/dataStores/DATA_STORE_ID/schemas/default_schema"
   

   Sostituisci quanto segue:

   • PROJECT_ID: l'ID progetto.
   • DATA_STORE_ID: l'ID del datastore.
