Modifying Instance Specifications

instance_id

Yes

String

Instance ID.

project_id

Yes

String

Project ID. For details, see Obtaining a Project ID.

spec_code

Yes

String

Flavor after the modification. The query method is as follows:

• Method 1: Log in to the DCS console, go to the instance creation page, and check the instance flavor.

• Method 2: Call the API used to query product flavors.

new_capacity

Yes

Integer

New memory size of the DCS instance, in GB.

For a single-node or master/standby DCS Redis 4.0 or later instance, the value can be 0.125, 0.25, 0.5, 1, 2, 4, 8, 16, 32, or 64. For a cluster DCS Redis 4.0 or later instance, the value can be 4, 8, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 512, 768, or 1024. For a read/write splitting DCS Redis 4.0 or later instance, the value can be 1, 2, 4, 8, 16, 32, 64.

For a single-node or master/standby DCS Memcached instance, the value can be 2, 4, 8, 16, 32, or 64.

In addition to integers, 0.125, 0.25, and 0.5 are also supported.

bss_param

No

BssParamEntity object

This parameter does not need to be set for pay-per-use instances.

reserved_ip

No

Array of strings

IP addresses to retain. Mandatory during cluster scale-in. If this parameter is not set, the system randomly deletes unnecessary shards.

change_type

No

String

Modification type. Mandatory when the number of replicas of a DCS Redis instance is modified.

• createReplication: adding replicas

• deleteReplication: deleting replicas

• addSharding: adding shards

• instanceType: changing the instance type. Currently, you can change a master/standby or read/write splitting DCS Redis 4.0/5.0/6.0 instance to the Proxy Cluster type, or from Proxy Cluster to master/standby or read/write splitting[, or from master/standby to read/write splitting].

available_zones

No

Array of strings

Code of the AZ where each replica is in. This parameter is mandatory when you add replicas to a DCS Redis instance. Before specifying an AZ, ensure that there are available resources in it. This parameter is mandatory when you delete replicas from a cluster instance.

For details, see Querying AZs.

node_list

No

Array of strings

ID of the replica to delete. This parameter is mandatory when you delete replicas of a master/standby or read/write splitting DCS Redis instance. Currently, only one replica can be deleted at a time.

For details, see Querying Details of Shards and Replicas.

execute_immediately

No

Boolean

Whether to apply the change immediately. The default value is true.

• true: Yes.

• false: No. Apply the change in the maintenance time window. Specification changes can be applied during the maintenance window only in some scenarios. For details, see Modifying Specifications.

enable_ipv6

No

Boolean

Parameter description:

Whether IPv6 is enabled.

Constraints:

N/A

Value range:

true: Yes

false: No

Default value:

false

is_auto_pay

No

String

Indicates whether fees are deducted automatically from the account balance. Non-automatic payment is used by default.

Value range:

• true: Fees are automatically deducted from the account balance.

• false: The order must be paid manually. This is the default value.

Note:

If this parameter is set to true, fees will be automatically deleted from the account balance. To use cash coupons, set this parameter to false and go to the Billing Center to make the payment.

If this parameter is set to false, go to Billing Center > Orders to pay for the order after modifying specifications or creating an instance. Otherwise, the order is always pending payment and the instance modification or creation is not considered successful.
