-<p>You can manipulate your data using the various <a href="/documentation/programming-guide/#transforms">transforms</a> provided in the Beam SDKs. To do this, you <strong>apply</strong> the trannsforms to your pipeline’s <code class="highlighter-rouge">PCollection</code> by calling the <code class="highlighter-rouge">apply</code> method on each <code class="highlighter-rouge">PCollection</code> that you want to process and passing the desired transform object as an argument.</p>

-<p>The following code shows how to <code class="highlighter-rouge">apply</code> a transform to a <code class="highlighter-rouge">PCollection</code> of strings.

-<p>Once your pipeline has applied all of its transforms, you’ll usually need to output the results. To output your pipeline’s final <code class="highlighter-rouge">PCollection</code>s, you apply a <code class="highlighter-rouge">Write</code> transform to that <code class="highlighter-rouge">PCollection</code>. <code class="highlighter-rouge">Write</code> transforms can output the elements of a <code class="highlighter-rouge">PCollection</code> to an external data sink, such as a database [...]

-<p>Your Beam program expresses a data processing pipeline, from start to finish. This section explains the mechanics of using the classes in the Beam SDKs to build a pipeline. To construct a pipeline using the classes in the Beam SDKs, your program will need to perform the following general steps:</p>
+<h1 id="side-input-patterns">Side input patterns</h1>
 
-<ul>
-  <li>Create a <code class="highlighter-rouge">Pipeline</code> object.</li>
-  <li>Use a <strong>Read</strong> or <strong>Create</strong> transform to create one or more <code class="highlighter-rouge">PCollection</code>s for your pipeline data.</li>
-  <li>Apply <strong>transforms</strong> to each <code class="highlighter-rouge">PCollection</code>. Transforms can change, filter, group, analyze, or otherwise process the elements in a <code class="highlighter-rouge">PCollection</code>. Each transform creates a new output <code class="highlighter-rouge">PCollection</code>, to which you can apply additional transforms until processing is complete.</li>
-  <li><strong>Write</strong> or otherwise output the final, transformed <code class="highlighter-rouge">PCollection</code>s.</li>
-  <li><strong>Run</strong> the pipeline.</li>
-</ul>
+<p>The samples on this page show you common Beam side input patterns. A side input is an additional input that your <code class="highlighter-rouge">DoFn</code> can access each time it processes an element in the input <code class="highlighter-rouge">PCollection</code>. For more information, see the <a href="/documentation/programming-guide/#side-inputs">programming guide section on side inputs</a>.</p>
 
-<h2 id="creating-your-pipeline-object">Creating Your Pipeline Object</h2>
+<h2 id="using-global-window-side-inputs-in-non-global-windows">Using global window side inputs in non-global windows</h2>
 
-<p>A Beam program often starts by creating a <code class="highlighter-rouge">Pipeline</code> object.</p>
+<p>You can retrieve side inputs from global windows to use them in a pipeline job with non-global windows, like a <code class="highlighter-rouge">FixedWindow</code>.</p>
 
-<p>In the Beam SDKs, each pipeline is represented by an explicit object of type <code class="highlighter-rouge">Pipeline</code>. Each <code class="highlighter-rouge">Pipeline</code> object is an independent entity that encapsulates both the data the pipeline operates over and the transforms that get applied to that data.</p>
+<p>To use global window side inputs in pipelines with non-global windows:</p>
 
-<p>To create a pipeline, declare a <code class="highlighter-rouge">Pipeline</code> object, and pass it some <a href="/documentation/programming-guide#configuring-pipeline-options">configuration options</a>.</p>
+<ol>
+  <li>
+    <p>Write a <code class="highlighter-rouge">DoFn</code> that periodically pulls data from a bounded source into a global window.</p>
 
-<div class="language-java highlighter-rouge"><pre class="highlight"><code><span class="c1">// Start by defining the options for the pipeline.</span>

-</div>
+    <p>b. Instantiate a data-driven trigger that activates on each element and pulls data from a bounded source.</p>
 
-<h2 id="reading-data-into-your-pipeline">Reading Data Into Your Pipeline</h2>
+    <p>c. Fire the trigger to pass the data into the global window.</p>
+  </li>
+  <li>
+    <p>Create the side input for downstream transforms. The side input should fit into memory.</p>
+  </li>
+</ol>
 
-<p>To create your pipeline’s initial <code class="highlighter-rouge">PCollection</code>, you apply a root transform to your pipeline object. A root transform creates a <code class="highlighter-rouge">PCollection</code> from either an external data source or some local data you specify.</p>
+<p>The global window side input triggers on processing time, so the main pipeline nondeterministically matches the side input to elements in event time.</p>
 
-<p>There are two kinds of root transforms in the Beam SDKs: <code class="highlighter-rouge">Read</code> and <code class="highlighter-rouge">Create</code>. <code class="highlighter-rouge">Read</code> transforms read data from an external source, such as a text file or a database table. <code class="highlighter-rouge">Create</code> transforms create a <code class="highlighter-rouge">PCollection</code> from an in-memory <code class="highlighter-rouge">java.util.Collection</code>.</p>
+<p>For instance, the following code sample uses a <code class="highlighter-rouge">Map</code> to create a <code class="highlighter-rouge">DoFn</code>. The <code class="highlighter-rouge">Map</code> becomes a <code class="highlighter-rouge">View.asSingleton</code> side input that’s rebuilt on each counter tick. The side input updates every 5 seconds in order to demonstrate the workflow. In a real-world scenario, the side input would typically update every few hours or once per day.</p>
 
-<p>The following example code shows how to <code class="highlighter-rouge">apply</code> a <code class="highlighter-rouge">TextIO.Read</code> root transform to read data from a text file. The transform is applied to a <code class="highlighter-rouge">Pipeline</code> object <code class="highlighter-rouge">p</code>, and returns a pipeline data set in the form of a <code class="highlighter-rouge">PCollection&lt;String&gt;</code>:</p>
