Querying Details About a Processing Task

Function

This API is used to obtain details about processing tasks, including feature analysis tasks and data processing tasks. You can specify the task_id parameter to obtain the details about a specific task.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.

Response Parameters

Status code: 200

**Table 2** Response body parameters
Parameter	Type	Description
create_time	Long	Time when a data processing task is created.
data_source	ProcessorDataSource object	Input of a data processing task. Either this parameter or inputs is delivered.
description	String	Description of a data processing task.
duration_seconds	Integer	Running time of data processing, in seconds.
error_msg	String	Error message. This field is displayed when the value of status is 3.
inputs	Array of ProcessorDataSource objects	Input channel list of a data processing task. Either this parameter or data_source is delivered.
is_current	Boolean	Whether the current task is the latest of the same type of this version.
name	String	Name of a data processing task.
result	Object	Output result of a data processing task. This field is displayed when status is set to 2 and is valid for a feature analysis task.
status	Integer	Status of a data processing task. Options: 0: initialized 1: running 2: completed 3: failed 4: stopped
task_id	String	ID of a data processing task.
template	TemplateParam object	Data processing template, such as the algorithm ID and parameters.
version_count	Integer	Version number of a data processing task.
version_id	String	Dataset version ID corresponding to a data processing task.
version_name	String	Dataset version name corresponding to a data processing task.
work_path	WorkPath object	Working directory of a data processing task.
workspace_id	String	Workspace ID of a data processing task. If no workspace is created, the default value is 0. If a workspace is created and used, use the actual value.

**Table 3** ProcessorDataSource
Parameter	Type	Description
name	String	Dataset name.
source	String	Data source path. Options: If type is set to OBS, source is an OBS path. If type is set to TASK, source is a task ID. If type is set to DATASET, source is a dataset ID. If type is set to CUSTOM and the API is called by resource tenants, set source to the project_id of the actual user. Otherwise, this field is left blank.
type	String	Data source type. Options: OBS: Data obtained from OBS TASK: Data processing task DATASET: Dataset CUSTOM: Data called by resource tenants
version_id	String	Version of a dataset.
version_name	String	Dataset version name.

**Table 4** TemplateParam
Parameter	Type	Description
id	String	Task type, which is the ID of a data processing template. Options: sys_data_analyse: feature analysis sys_data_cleaning: data cleansing sys_data_augmentation: data augmentation sys_data_validation: data validation sys_data_selection: data filtering
name	String	Template name.
operator_params	Array of OperatorParam objects	Operator parameter list.

**Table 5** OperatorParam
Parameter	Type	Description
advanced_params_switch	Boolean	Advanced parameter switch.
id	String	ID of an operator.
name	String	Name of an operator.
params	Object	Operator parameter. The parameter type is map<string,object>. Currently, object only supports the types of Boolean, Integer, Long, String, List[/topic/body/section/table/tgroup/tbody/row/entry/p/br {""}) (br] and Map<String,String>. For two special scenarios of object detection and image classification in a data preprocessing task, the value of task_type is object_detection or image_classification.

**Table 6** WorkPath
Parameter	Type	Description
name	String	Dataset name.
output_path	String	Output path, for example, /datasets/demo.
path	String	Working path. Options: If type is set to OBS, source is an OBS path. If type is set to DATASET, source is a dataset ID.
type	String	Type of a working path. Options: OBS: OBS path DATASET: dataset
version_id	String	Version of a dataset.
version_name	String	Name of a dataset version. The value can contain 0 to 32 characters. Only digits, letters, underscores (_), and hyphens (-) are allowed.
