-- Allows you to purchase reserved nodes. Amazon Redshift offers a
-- predefined set of reserved node offerings. You can purchase one or more
-- of the offerings. You can call the DescribeReservedNodeOfferings API to
-- obtain the available reserved node offerings. You can call this API by
-- providing a specific reserved node offering and the number of nodes you
-- want to reserve.
--
-- For more information about reserved node offerings, go to
-- <https://docs.aws.amazon.com/redshift/latest/mgmt/purchase-reserved-node-instance.html Purchasing Reserved Nodes>
