VPC network ID

Subnet ID.

Database type

Enumeration values:

• MYSQL: MYSQL

Database version

Enumeration values:

• 5.7: MySQL 5.7 version
• 8.0: MySQL 8.0 version

Project ID.

Required when DbMode is NORMAL or left empty
Number of Cpu cores of a NORMAL instance

Required when DbMode is NORMAL or not specified
Normal instance memory in GB

Instance count

Value range: [1, 16]

Default value: 2

• A value of 2 means one rw instance + one ro instance.
• The transmitted n means 1 rw instance + n-1 ro instances (identical specifications).
• If you need a more precise cluster composition, please use InstanceInitInfos.
• The value set by this parameter is applicable to provisioned resource clusters. To set the specifications and quantity of instances in a Serverless cluster, please use the InstanceInitInfo structure in InstanceInitInfos.n.

This parameter is meaningless and abandoned.
Storage size, in GB.

Cluster name, length less than 64 characters. Each character can be an uppercase/lowercase letter, digit, or special symbol ('-', '_', '.')

Account password (8-64 characters, containing any three of the following: uppercase and lowercase letters, digits, and symbols ~!@#$%^&*_-+=`|(){}[]:;'<>,.?/)

Port. Default value: 3306. Value range: [0, 65535)

Billing mode

Enumeration values:

• 0: pay-as-you-go
• 1: yearly/monthly subscription

Default value: 0

Number of clusters to purchase. Optional value range: [1,50]. Default value: 1

Rollback type

Enumeration values:

• noneRollback: No rollback
• snapRollback: Snapshot rollback
• timeRollback: Point-in-time rollback

Snapshot rollback refers to snapshotId; point-in-time rollback refers to queryId. If it is 0, you need to determine whether the time point is valid.

During rollback, import the source cluster ID to search for the source poolId

Point-in-time rollback, specified time; snapshot rollback, snapshot time

This parameter is meaningless and abandoned.
Point-in-time rollback, allowed range of the specified time

Storage limit of a regular instance, in GB
When DbType is MYSQL and the storage billing mode is prepaid, this parameter cannot exceed the maximum storage specification corresponding to the cpu and memory

Annual and monthly subscription duration

Annual and monthly subscription duration measurement unit, ['s','d','m','y']

Whether Annual/Monthly Subscription is auto-renewed

Enumeration values:

• 0: default renewal method
• 1: auto-renewal
• 2: no auto-renewal

Default value: 0

Whether to automatically select a voucher. 1: Yes; 0: No. Default is 0.

Enumeration values:

• 1: Yes
• 0: No

Default value: 0

Instance count (this parameter is deprecated and only accommodative for existing use)

Order Source

tag array information that needs to be bound for cluster creation

DB type

Enumeration values:

• NORMAL: normal instance
• SERVERLESS: serverless instance

Default value: NORMAL

Selectable when DbType is MYSQL (default: NORMAL)

Required when DbMode is SERVERLESS
Minimum cpu value. For the optional range, see the API return of DescribeServerlessInstanceSpecs

Required when DbMode is SERVERLESS:
maximum value of cpu. For the optional range, see the API return of DescribeServerlessInstanceSpecs

Whether to auto pause

Enumeration values:

• yes: Yes
• no: No

Default value: yes

Takes effect when DbMode is SERVERLESS

When DbMode is SERVERLESS, specify the delay for Cluster Auto-Pause in seconds. Optional range: [600,691200]
Default value: 600

Cluster storage billing mode. Pay-as-you-go: 0; monthly subscription: 1. Default is pay-as-you-go.
When DbType is MYSQL and the cluster compute billing mode is postpaid (including when DbMode is SERVERLESS), the storage billing mode can only be pay-as-you-go.
Rollback and clone do not support monthly subscription storage.

Security group id array

Alarm policy Id array

Parameter array. It temporarily supports character_set_server (utf8 | latin1 | gbk | utf8mb4) and lower_case_table_names. 1: not case-sensitive; 0: case-sensitive.

Transaction mode

Enumeration values:

• 0: Place order and pay
• 1: Place order

Default value: 0

Parameter template ID, which can be obtained by querying parameter template information through DescribeParamTemplates.

Multi-AZ address

Instance initialization configuration information, primarily used for selecting different specification instances during cluster purchase.

Global database unique ID

Database proxy configuration

Whether to automatically archive

Enumeration values:

• yes: Yes
• no: No

Default value: no

This parameter takes effect only when the primary instance of the current cluster is SERVERLESS

Archiving processing time after pausing

Unit: hour

Default value: 12

This parameter takes effect only when the primary instance of the current cluster is SERVERLESS

Cluster level, nullable. For example, P0, P1. (This field can be ignored.)

Kernel minor version number.

Synchronization method. Available values: async, semisync, sync.

Semi-sync timeout period, in milliseconds. To ensure business stability, semi-sync replication has a degradation logic. When the primary availability zone cluster waits for the standby availability zone cluster to confirm a transaction, if the timeout period is exceeded, the replication method will degrade to asynchronous replication.

Value range: [1000, 4294967295]

Unit: ms

Default value: 10000

Frozen transaction ID

Order ID.

Resource ID list (this field is no longer maintained. Please use the dealNames field to query the api DescribeResourcesByDealName to obtain resource IDs)

Cluster ID list (this field is no longer maintained. Please use the dealNames field to query the DescribeResourcesByDealName API to get the cluster ID)
