-- | Deletes a stream and all its shards and data. You must shut down any
-- applications that are operating on the stream before you delete the stream.
-- If an application attempts to operate on a deleted stream, it will receive
-- the exception 'ResourceNotFoundException'.
--
-- If the stream is in the 'ACTIVE' state, you can delete it. After a 'DeleteStream'
-- request, the specified stream is in the 'DELETING' state until Amazon Kinesis
-- completes the deletion.
--
-- Note: Amazon Kinesis might continue to accept data read and write
-- operations, such as 'PutRecord', 'PutRecords', and 'GetRecords', on a stream in the 'DELETING' state until the stream deletion is complete.
--
-- When you delete a stream, any shards in that stream are also deleted, and
-- any tags are dissociated from the stream.
--
-- You can use the 'DescribeStream' operation to check the state of the stream,
-- which is returned in 'StreamStatus'.
--
-- 'DeleteStream' has a limit of 5 transactions per second per account.
