Creating a Queue

Function

This API is used to create a queue. The queue will be bound to specified compute resources.

It takes 5 to 15 minutes to start a job using a new queue for the first time.

URI

URI format
POST /v1.0/{project_id}/queues

Parameter description

**Table 1** URI parameter
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID, which is used for resource isolation. For details about how to obtain its value, see Obtaining a Project ID.

Request

**Table 2** Request parameters
Parameter	Mandatory	Type	Description
queue_name	Yes	String	Name of a newly created resource queue. The name can contain only digits, letters, and underscores (_), but cannot contain only digits or start with an underscore (_). Length range: 1 to 128 characters. NOTE: The queue name is case-insensitive. The uppercase letters will be automatically converted to lowercase letters.
queue_type	No	String	Queue type. The options are as follows: sql: Queues used to run SQL jobs general: Queues used to run Flink and Spark Jar jobs. NOTE: If the type is not specified, the default value sql is used.
description	No	String	Description of a queue.
cu_count	Yes	Integer	Minimum number of CUs that are bound to a queue. Currently, the value can only be 16, 64, or 256.
charging_mode	No	Integer	Billing mode of a queue. This value can only be set to 1, indicating that the billing is based on the CUH used.
enterprise_project_id	No	String	Enterprise project ID. The value 0 indicates the default enterprise project. NOTE: Users who have enabled Enterprise Management can set this parameter to bind a specified project.
platform	No	String	CPU architecture of compute resources. x86_64
resource_mode	No	Integer	Queue resource mode. The options are as follows: 0: shared resource mode 1: dedicated resource mode
labels	No	Array of Strings	Tag information of the queue to be created. Currently, the tag information includes whether the queue is cross-AZ (JSON string). The value can only be 2, that is, a dual-AZ queue whose compute resources are distributed in two AZs is created.
feature	No	String	Indicates the queue feature. The options are as follows: basic: basic type ai: AI-enhanced (Only the SQL x86_64 dedicated queue supports this option.) The default value is basic. NOTE: For an enhanced AI queue, an AI image is loaded in the background. The image integrates AI algorithm packages based on the basic image. For details, see Data Lake Insight User Guide.
tags	No	Array of Objects	Queue tags for identifying cloud resources. A tag consists of a key and tag value. For details, see Table 3.

**Table 3** tags parameters
Parameter	Mandatory	Type	Description
Key	Yes	String	Tag key. NOTE: A tag key can contain a maximum of 128 characters. Only letters, digits, spaces, and special characters (_.:=+-@) are allowed, but the value cannot start or end with a space or start with _sys_.
value	Yes	String	Tag value. NOTE: A tag value can contain a maximum of 225 characters. Only letters, digits, spaces, and special characters (_.:=+-@) are allowed. The value cannot start or end with a space.

Response

**Table 4** Response parameters
Parameter	Mandatory	Type	Description
is_success	No	Boolean	Indicates whether the request is successfully executed. Value true indicates that the request is successfully executed.
message	No	String	System prompt. If execution succeeds, the parameter setting may be left blank.
queue_name	No	String	Name of the created queue. NOTE: The queue name is case-insensitive. The uppercase letters will be automatically converted to lowercase letters.

Example Request

Create a dedicated general-purpose queue named queue1, with specifications of 16 CUs and compute resources distributed in two AZs.

{
    "queue_name": "queue1",
    "description": "test",
    "cu_count": 16,
    "resource_mode": 1,
    "enterprise_project_id": "0",
    "queue_type": "general",
    "labels": ["multi_az=2"]
}

Creating a queue in a specified elastic resource pool

{
    "queue_name": "queue2",
    "description": "test_esp",
    "cu_count": 16,
    "resource_mode": 1,
    "enterprise_project_id": "0",
    "queue_type": "general",
    "labels": ["multi_az=2"],
    "elastic_resource_pool_name": "elastic_pool_0622_10"
}

Example Response

{
  "is_success": true,
  "message": "",
  "queue_name": "queue1"
}

Status Codes

Table 5 describes the status code.

**Table 5** Status codes
Status Code	Description
200	The job is created successfully.
400	Request error.
500	Internal service error.

Error Codes

If an error occurs when this API is invoked, the system does not return the result similar to the preceding example, but returns the error code and error information. For details, see Error Codes.
