Request parameters

Parameter	Type	Required	Description	Example
DBClusterId	string	Yes	The ID of the cluster. Note You can call the DescribeDBClusters operation to query the details of the clusters that belong to your Alibaba Cloud account, such as cluster IDs.	pc-*****************

RuleConfig	string	No	The parameter that is used to specify the masking rule that you want to modify and the value in the JSON format. All parameter values are of the string type. Example: `{"auto": {"databases": ["db1"], "tables": ["tb1"], "columns": ["c1,c2"] }, "description": "This rule will be applied to the columns c1 and c2 in table t1", "enabled": true, "applies_to": ["user"]}`. Where, `"auto"`: specifies that the dynamic masking algorithm is supported. This parameter is required. `"databases"`: Optional. The names of databases to which the masking rule is applied.
