Last Updated:Apr 14, 2026

Queries the automatic SQL throttling rules of a database instance.

Operation description

Before you call this operation, take note of the following items:

  • If you use an SDK to call API operations of Database Autonomy Service (DAS), you must set the region ID to cn-shanghai.

  • The database instance that you want to manage must be of one of the following types:

    • ApsaraDB RDS for MySQL High-availability Edition or Enterprise Edition that runs MySQL 5.6, MySQL 5.7, or MySQL 8.0

    • PolarDB for MySQL Cluster Edition that runs MySQL 5.6, MySQL 5.7, or MySQL 8.0

Try it now

Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

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.

Request parameters

Parameter

Type

Required

Description

Example

ConsoleContext

string

No

The reserved parameter.

InstanceIds

string

No

The database instance IDs.

  • Set this parameter to a JSON array that consists of multiple instance IDs. Separate instance IDs with commas (,). Example: ['Instance ID1','Instance ID2'].

  • By default, if you leave this parameter empty, all database instances for which the automatic SQL throttling feature has been enabled within the current Alibaba Cloud account are returned. The following types of database instances are returned:

    • Database instances for which the automatic SQL throttling feature is currently enabled.

    • Database instances for which the automatic SQL throttling feature was once enabled but is currently disabled. Released database instances are not included.
