Modifying Specifications of Instances with New Flavors
Function
This API is used to modify instance specifications.
URI
POST /v2/{engine}/{project_id}/instances/{instance_id}/extend
Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
project_id |
Yes |
String |
Project ID. For details, see Obtaining a Project ID. |
instance_id |
Yes |
String |
Instance ID. |
engine |
Yes |
String |
Message engine, which is rabbitmq. Default: rabbitmq |
Request Parameters
Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
oper_type |
Yes |
String |
Type of the change. Value: storage: Expand the storage space without adding brokers. horizontal: Add brokers without resizing the storage space of each broker. vertical: Modify the underlying flavor of brokers without adding brokers or storage space. |
new_storage_space |
No |
Integer |
New storage space. This parameter is valid and mandatory when oper_type is set to storage or horizontal. Instance storage space = Number of brokers x Storage space of each broker. If oper_type is set to storage, the number of brokers remains unchanged, and the storage space of each broker must be expanded by at least 100 GB. If oper_type is set to horizontal, the storage space of each broker remains unchanged. |
new_product_id |
No |
String |
Flavor, such as c6.8u16g.cluster. This parameter is valid and mandatory when oper_type is set to vertical. |
new_broker_num |
No |
Integer |
This parameter is valid only when oper_type is set to horizontal. |
new_spec_code |
No |
String |
Old flavor, such as dms.instance.rabbitmq.cluster.c3.8u16g. When oper_type is set to horizontal, the value is dms.instance.rabbitmq.cluster.c3.8u16g.5 (5 is the broker quantity.) |
Response Parameters
Status code: 200
Parameter |
Type |
Description |
---|---|---|
job_id |
String |
ID of the specification modification task. |
Example Requests
-
Expanding the storage space (pay-per-use, old flavors). new_spec_code is the original specification.
POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend { "new_storage_space" : 600, "oper_type" : "storage", "new_spec_code" : "dms.instance.rabbitmq.cluster.c3.2u4g.3" }
-
Adding brokers (pay-per-use, old flavors). new_storage_space is the space of the original specification. new_spec_code is dms.instance.rabbitmq.cluster.c3.2u4g.5 (5 is the broker quantity.)
POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend { "new_storage_space" : 600, "oper_type" : "horizontal", "new_spec_code" : "dms.instance.rabbitmq.cluster.c3.2u4g.5" }
-
Increasing broker flavors (pay-per-use, old flavors). For new_spec_code, replace the original specification with the new one. For example, replace 2u4g with 4u8g.
POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend { "new_storage_space" : 600, "oper_type" : "vertical", "new_spec_code" : "dms.instance.rabbitmq.cluster.c3.2u4g.5" }
-
Expanding the storage space (pay-per-use)
POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend { "new_storage_space" : 600, "oper_type" : "storage" }
-
