Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation
adb:DescribeSQLPlan	get	DBCluster acs:adb:{#regionId}:{#accountId}:dbcluster/{#DBClusterId}	none	none

Request parameters

Parameter	Type	Required	Description	Example
DBClusterId	string	Yes	The cluster ID. Note You can call the DescribeDBClusters operation to query the information about all AnalyticDB for MySQL clusters within a region, including cluster IDs.	am-****************
ProcessId	string	Yes	The query ID. Note You can call the DescribeProcessList operation to query the IDs of queries that are being executed.	202105271604431720161662490345*******
