-- DescribeEndpoints returns a list of available endpoints to make
-- Timestream API calls against. This API is available through both Write
-- and Query.
--
-- Because the Timestream SDKs are designed to transparently work with the
-- service’s architecture, including the management and mapping of the
-- service endpoints, /it is not recommended that you use this API unless/:
--
-- -   You are using
--     <https://docs.aws.amazon.com/timestream/latest/developerguide/VPCEndpoints VPC endpoints (Amazon Web Services PrivateLink) with Timestream>
--
-- -   Your application uses a programming language that does not yet have
--     SDK support
--
-- -   You require better control over the client-side implementation
--
-- For detailed information on how and when to use and implement
-- DescribeEndpoints, see
-- <https://docs.aws.amazon.com/timestream/latest/developerguide/Using.API.html#Using-API.endpoint-discovery The Endpoint Discovery Pattern>.
