1. API Description

Domain name for API request: emr.intl.tencentcloudapi.com.

This API is used to create a Serverless HBase instance.- If the API call is successful, a Serverless HBase instance will be created. If the instance creation request is successful, the InstanceId of the created instance and the RequestID of the request will be returned.- This is an asynchronous API. The operation is not completed immediately when the API call returns. The instance operation result can be viewed by calling DescribeInstancesList to view the StatusDesc status of the current instance.

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

InstanceName	Yes	String	Instance name.
PayMode	Yes	Integer	Instance billing mode. 0 indicates postpaid, i.e., pay-as-you-go.
DiskType	Yes	String	Instance storage type. Fill in CLOUD_HSSD to represent high-performance cloud storage.
DiskSize	Yes	Integer	The disk capacity of a single node of the instance, in GB. The disk capacity of a single node should be greater than or equal to 100 and less than or equal to 250 x the number of CPU cores. The capacity adjustment step is 100.
NodeType	Yes	String	Instance node specification. You can fill in 4C16G, 8C32G, 16C64G, or 32C128G, which is case-insensitive.
ZoneSettings.N	Yes	Array of ZoneSetting	Detailed configuration of the instance AZ. Currently, multiple availability zones are supported. The number of AZs must be 1 or 3, including the region names, VPC information, and number of nodes. The total number of nodes across all zones must be greater than or equal to 3 and less than or equal to 50.
Tags.N	No	Array of Tag	List of tags to be bound to the instance.
PrePaySetting	No	PrePaySetting	Prepaid parameter.
ClientToken	No	String	The unique random identifier with a time efficiency of 5 minutes, which needs to be specified by the caller to prevent the client from creating resources repeatedly. For example: a9a90aa6---****-fae360632808.
DeploymentMode	No	String

3. Output Parameters

Parameter Name	Type	Description
InstanceId	String	Instance unique identifier (string).
RequestId	String	The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.
