// Accepts a structured query language (SQL) SELECT command and an aggregator to

// configurations matching the properties. For more information about query
// components, see the Query Components  (https://docs.aws.amazon.com/config/latest/developerguide/query-components.html)
// section in the Config Developer Guide. If you run an aggregation query (i.e.,
// using GROUP BY or using aggregate functions such as COUNT ; e.g., SELECT
// resourceId, COUNT(*) WHERE resourceType = 'AWS::IAM::Role' GROUP BY resourceId )

// page size is set to 500. If you run a non-aggregation query (i.e., not using
// GROUP BY or aggregate function; e.g., SELECT * WHERE resourceType =
// 'AWS::IAM::Role' ) and do not specify the MaxResults or the Limit query
// parameters, the default page size is set to 25.
