-- Provides information about the queues for the specified Amazon Connect
-- instance.
--
-- If you do not specify a @QueueTypes@ parameter, both standard and agent
-- queues are returned. This might cause an unexpected truncation of
-- results if you have more than 1000 agents and you limit the number of
-- results of the API call in code.
--
-- For more information about queues, see
-- <https://docs.aws.amazon.com/connect/latest/adminguide/concepts-queues-standard-and-agent.html Queues: Standard and Agent>
-- in the /Amazon Connect Administrator Guide/.
--
-- This operation returns paginated results.
