deleteConfigRule

Deletes the specified Config rule and all of its evaluation results.

Config sets the state of a rule to DELETING until the deletion is complete. You cannot update a rule while it is in this state. If you make a PutConfigRule or DeleteConfigRule request for the rule, you will receive a ResourceInUseException.

You can check the state of a rule by using the DescribeConfigRules request.

Recommendation: Consider excluding the AWS::Config::ResourceCompliance resource type from recording before deleting rules

Deleting rules creates configuration items (CIs) for AWS::Config::ResourceCompliance that can affect your costs for the configuration recorder. If you are deleting rules which evaluate a large number of resource types, this can lead to a spike in the number of CIs recorded.

To avoid the associated costs, you can opt to disable recording for the AWS::Config::ResourceCompliance resource type before deleting rules, and re-enable recording after the rules have been deleted.

However, since deleting rules is an asynchronous process, it might take an hour or more to complete. During the time when recording is disabled for AWS::Config::ResourceCompliance, rule evaluations will not be recorded in the associated resource’s history.
