--
-- Accepts a structured query language (SQL) SELECT command and an
-- aggregator to query configuration state of Amazon Web Services resources
-- across multiple accounts and regions, performs the corresponding search,
-- and returns resource configurations matching the properties.
--
-- For more information about query components, see the
-- <https://docs.aws.amazon.com/config/latest/developerguide/query-components.html Query Components>
-- 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@)
-- and do not specify the @MaxResults@ or the @Limit@ query parameters, the
-- default 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.
--
-- This operation returns paginated results.
