--
-- Decreases the Kinesis data stream\'s retention period, which is the
-- length of time data records are accessible after they are added to the
-- stream. The minimum value of a stream\'s retention period is 24 hours.
--
-- When invoking this API, it is recommended you use the @StreamARN@ input
-- parameter rather than the @StreamName@ input parameter.
--
-- This operation may result in lost data. For example, if the stream\'s
-- retention period is 48 hours and is decreased to 24 hours, any data
-- already in the stream that is older than 24 hours is inaccessible.
