    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

    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.

      • MaxExecutionTime: the maximum execution duration of the SQL pattern within the time range to query.
      • AveragePeakMemory: the average peak memory usage of the SQL pattern within the time range to query.
      • MaxPeakMemory: the maximum peak memory usage of the SQL pattern within the time range to query.
      • AverageScanSize: the average amount of data scanned based on the SQL pattern within the time range to query.
      • MaxScanSize: the maximum amount of data scanned based on the SQL pattern within the time range to query.
