-- Returns events related to DB instances, DB clusters, DB parameter
-- groups, DB security groups, DB snapshots, DB cluster snapshots, and RDS
-- Proxies for the past 14 days. Events specific to a particular DB
-- instance, DB cluster, DB parameter group, DB security group, DB
-- snapshot, DB cluster snapshot group, or RDS Proxy can be obtained by
-- providing the name as a parameter.

-- in the /Amazon Aurora User Guide/.
--
-- By default, RDS returns events that were generated in the past hour.
--
-- This operation returns paginated results.
