This list constraint defines the set of predefined policies that can be enforced for VPC flow logs.

By default VPC flow logs may be configured with any settings in each subnet.
This constraint enforces the enabling of flow logs for all subnetworks in scope with a required minimum sampling rate.
Specify one or more of the following valid values:
[ESSENTIAL (allows values >= 0.1 and < 0.5),
LIGHT (allows values >= 0.5 and < 1.0),
COMPREHENSIVE (allows values == 1.0)].

All flows of the network has to be logged for auditing purposes.
With this policy, all VPC subnets created will have logging enabled.

The only impact is the slight increased to the cost incurred with the bill due to additional logging.
