+ <ul>
+ <li>
+ Tumbling Windows: A tumbling window defines a series of non-overlapping, fixed size, contiguous intervals.
+ <li>
+ Session Windows: A session window groups a <a href="../../../../../org/apache/samza/operators/MessageStream.html" title="interface in org.apache.samza.operators"><code>MessageStream</code></a> into sessions.
+ A <i>session</i> captures some period of activity over a <a href="../../../../../org/apache/samza/operators/MessageStream.html" title="interface in org.apache.samza.operators"><code>MessageStream</code></a>.
+ The boundary for a session is defined by a <code>sessionGap</code>. All messages that that arrive within
+ the gap are grouped into the same session.
+ <li>
+ Global Windows: A global window defines a single infinite window over the entire <a href="../../../../../org/apache/samza/operators/MessageStream.html" title="interface in org.apache.samza.operators"><code>MessageStream</code></a>.
+ An early trigger must be specified when defining a global window.
+ </ul>
