Delete a feature

You can delete specific features from a feature group. Deleting a feature unregisters the feature column from the Feature Registry and doesn't affect the data in the column in the registered BigQuery source table or view. You can create another feature in any feature group to register the same column again, if necessary.

Use the following sample to delete a feature from a feature group.

REST

To delete a Feature resource, send a DELETE request by using the features.delete method.

Before using any of the request data, make the following replacements:

  • LOCATION_ID: Region where the feature group is located, such as us-central1.
  • PROJECT_ID: Your project ID.
  • FEATURE_GROUP_NAME: The name of the feature group containing the feature.
  • FEATURE_NAME: The name of the feature that you want to delete.

HTTP method and URL: 

DELETE https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featureGroups/FEATURE_GROUP_NAME/features/FEATURE_NAME

To send your request, choose one of these options:

curl

Execute the following command: 

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featureGroups/FEATURE_GROUP_NAME/features/FEATURE_NAME"

PowerShell

Execute the following command: 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method DELETE `
    -Headers $headers `
    -Uri "https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featureGroups/FEATURE_GROUP_NAME/features/FEATURE_NAME" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

"name": "projects/PROJECT_NUMBER/locations/LOCATION_ID/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.aiplatform.v1.DeleteOperationMetadata",
    "genericMetadata": {
      "createTime": "2023-09-25T18:52:42.092928Z",
      "updateTime": "2023-09-25T18:52:42.092928Z"
    }
  },
  "done": true,
  "response": {
    "@type": "type.googleapis.com/google.protobuf.Empty"
  }
}
