-- | Provides options for how often Config delivers configuration snapshots
-- to the Amazon S3 bucket in your delivery channel.
--
-- The frequency for a rule that triggers evaluations for your resources
-- when Config delivers the configuration snapshot is set by one of two
-- values, depending on which is less frequent:
--
-- -   The value for the @deliveryFrequency@ parameter within the delivery
--     channel configuration, which sets how often Config delivers
--     configuration snapshots. This value also sets how often Config
--     invokes evaluations for Config rules.
--
-- -   The value for the @MaximumExecutionFrequency@ parameter, which sets
--     the maximum frequency with which Config invokes evaluations for the
--     rule. For more information, see ConfigRule.
--
-- If the @deliveryFrequency@ value is less frequent than the
-- @MaximumExecutionFrequency@ value for a rule, Config invokes the rule
-- only as often as the @deliveryFrequency@ value.
--
-- 1.  For example, you want your rule to run evaluations when Config
--     delivers the configuration snapshot.
--
-- 2.  You specify the @MaximumExecutionFrequency@ value for @Six_Hours@.
--
-- 3.  You then specify the delivery channel @deliveryFrequency@ value for
--     @TwentyFour_Hours@.
--
-- 4.  Because the value for @deliveryFrequency@ is less frequent than
--     @MaximumExecutionFrequency@, Config invokes evaluations for the rule
--     every 24 hours.
--
-- You should set the @MaximumExecutionFrequency@ value to be at least as
-- frequent as the @deliveryFrequency@ value. You can view the
-- @deliveryFrequency@ value by using the @DescribeDeliveryChannnels@
-- action.
--
-- To update the @deliveryFrequency@ with which Config delivers your
-- configuration snapshots, use the @PutDeliveryChannel@ action.
--
-- /See:/ 'newConfigSnapshotDeliveryProperties' smart constructor.
