Properties

ExcludedFields

public RepeatedField<string> ExcludedFields { get; }

Fields that will be excluded in the prediction instance that is sent to the Model.

Excluded will be attached to the batch prediction output if [key_field][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.key_field] is not specified.

When excluded_fields is populated, [included_fields][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.included_fields] must be empty.

The input must be JSONL with objects at each line, BigQuery or TfRecord.

Property Value
Type	Description
RepeatedFieldstring

IncludedFields

public RepeatedField<string> IncludedFields { get; }

Fields that will be included in the prediction instance that is sent to the Model.

If [instance_type][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.instance_type] is array, the order of field names in included_fields also determines the order of the values in the array.

When included_fields is populated, [excluded_fields][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.excluded_fields] must be empty.

The input must be JSONL with objects at each line, BigQuery or TfRecord.

Property Value
Type	Description
RepeatedFieldstring

InstanceType

public string InstanceType { get; set; }

The format of the instance that the Model accepts. Vertex AI will convert compatible [batch prediction input instance formats][google.cloud.aiplatform.v1.BatchPredictionJob.InputConfig.instances_format] to the specified format.

Supported values are:

• object: Each input is converted to JSON object format.

  • For bigquery, each row is converted to an object.
  • For jsonl, each line of the JSONL input must be an object.
  • Does not apply to csv, file-list, tf-record, or tf-record-gzip.

• array: Each input is converted to JSON array format.

  • For bigquery, each row is converted to an array. The order of columns is determined by the BigQuery column order, unless [included_fields][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.included_fields] is populated. [included_fields][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.included_fields] must be populated for specifying field orders.
  • For jsonl, if each line of the JSONL input is an object, [included_fields][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.included_fields] must be populated for specifying field orders.
  • Does not apply to csv, file-list, tf-record, or tf-record-gzip.

If not specified, Vertex AI converts the batch prediction input as follows:

• For bigquery and csv, the behavior is the same as array. The order of columns is the same as defined in the file or table, unless [included_fields][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.included_fields] is populated.
• For jsonl, the prediction instance format is determined by each line of the input.
• For tf-record/tf-record-gzip, each record will be converted to an object in the format of {"b64": <value>}, where <value> is the Base64-encoded string of the content of the record.
• For file-list, each file in the list will be converted to an object in the format of {"b64": <value>}, where <value> is the Base64-encoded string of the content of the file.

Property Value
Type	Description
string

KeyField

public string KeyField { get; set; }

The name of the field that is considered as a key.

The values identified by the key field is not included in the transformed instances that is sent to the Model. This is similar to specifying this name of the field in [excluded_fields][google.cloud.aiplatform.v1.BatchPredictionJob.InstanceConfig.excluded_fields]. In addition, the batch prediction output will not include the instances. Instead the output will only include the value of the key field, in a field named key in the output:

• For jsonl output format, the output will have a key field instead of the instance field.
• For csv/bigquery output format, the output will have have a key column instead of the instance feature columns.

The input must be JSONL with objects at each line, CSV, BigQuery or TfRecord.
