:SetPolarFsFileQuota

Last Updated:Mar 18, 2026

Sets file quota rules for a specified directory in a Polarlakebase instance.

Operation description

Request description

This operation sets file quota rules for a directory in a Polarlakebase instance. Configure the FilePathQuotas parameter to specify the directory and its quota properties. The path specified in FilePathId must be an absolute path from the root directory, not a mount target path. Use the Strategy parameter to control how the rule applies to existing files. By default, the rule is applied only if no other rule exists for the directory.

Notes

  • The FilePathQuotas list can contain a maximum of 21 items.

  • To apply the rule to multiple levels of subdirectories under FilePathId, set the MaxDepth parameter. To traverse all subdirectory levels, set this parameter to 0.

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.
