--
-- Configures options for
-- <https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html asynchronous invocation>
-- on a function, version, or alias. If a configuration already exists for
-- a function, version, or alias, this operation overwrites it. If you
-- exclude any settings, they are removed. To set one option without
-- affecting existing settings for other options, use
-- UpdateFunctionEventInvokeConfig.
--
-- By default, Lambda retries an asynchronous invocation twice if the
-- function returns an error. It retains events in a queue for up to six
-- hours. When an event fails all processing attempts or stays in the
-- asynchronous invocation queue for too long, Lambda discards it. To
-- retain discarded events, configure a dead-letter queue with
-- UpdateFunctionConfiguration.
--
-- To send an invocation record to a queue, topic, function, or event bus,
-- specify a
-- <https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html#invocation-async-destinations destination>.
-- You can configure separate destinations for successful invocations
-- (on-success) and events that fail all processing attempts (on-failure).
-- You can configure destinations in addition to or instead of a
-- dead-letter queue.
