ApsaraDB for MongoDB:ModifyNodeSpecBatch

Last Updated:Jan 26, 2026

Changes the configuration of one or more Mongos or shard nodes in an ApsaraDB for MongoDB sharded cluster instance.

Operation description

Before you call this operation, ensure that you understand the billing methods and pricing of ApsaraDB for MongoDB.

This operation applies only to ApsaraDB for MongoDB sharded cluster instances.

When you upgrade or downgrade multiple sharded cluster instances in a batch, the target instance types are subject to certain constraints. For example, if you expand storage capacity, the target capacity must be greater than or equal to the current capacity. If the instances have different instance types, the system randomly selects the instance type of one instance and applies its constraints to the entire batch. This may cause the upgrade or downgrade to fail. If you cannot upgrade or downgrade instances in a batch, you can use the ModifyNodeSpec operation to change the configuration of a single sharded cluster instance.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
