<pre>
Map from the input parameter in the definition to the real stream.
E.g., suppose you had a stream source operator named "input-0" and you try
to receive from the real stream "stream-0". You can add the following
mapping: [input-0: stream-0].

<code>map&lt;string, string&gt; input_streams_mapping = 6;</code>
