+&lt;p>The more general way to combine elements, and the most flexible, is with a class that inherits from &lt;code>CombineFn&lt;/code>.&lt;/p>

+&lt;p>&lt;a href="https://beam.apache.org/releases/pydoc/current/apache_beam.transforms.core.html#apache_beam.transforms.core.CombineFn.create_accumulator">&lt;code>CombineFn.create_accumulator()&lt;/code>&lt;/a>:
+This creates an empty accumulator.
+For example, an empty accumulator for a sum would be &lt;code>0&lt;/code>, while an empty accumulator for a product (multiplication) would be &lt;code>1&lt;/code>.&lt;/p>
+&lt;/li>
+&lt;li>
+&lt;p>&lt;a href="https://beam.apache.org/releases/pydoc/current/apache_beam.transforms.core.html#apache_beam.transforms.core.CombineFn.add_input">&lt;code>CombineFn.add_input()&lt;/code>&lt;/a>:
+Called &lt;em>once per element&lt;/em>.
+Takes an accumulator and an input element, combines them and returns the updated accumulator.&lt;/p>
+&lt;/li>
+&lt;li>
+&lt;p>&lt;a href="https://beam.apache.org/releases/pydoc/current/apache_beam.transforms.core.html#apache_beam.transforms.core.CombineFn.merge_accumulators">&lt;code>CombineFn.merge_accumulators()&lt;/code>&lt;/a>:
+Multiple accumulators could be processed in parallel, so this function helps merging them into a single accumulator.&lt;/p>
+&lt;/li>

+&lt;p>&lt;a href="https://beam.apache.org/releases/pydoc/current/apache_beam.transforms.core.html#apache_beam.transforms.core.CombineFn.extract_output">&lt;code>CombineFn.extract_output()&lt;/code>&lt;/a>:

 Schemas provide us a type-system for Beam records that is independent of any specific programming-language type. There might be multiple Java classes that all have the same schema (for example a Protocol-Buffer class or a POJO class), and Beam will allow us to seamlessly convert between these types.
 Schemas also provide a simple way to reason about types across different programming-language APIs.
 For more information, see the <a href=/documentation/programming-guide/#what-is-a-schema>programming guide section on Schemas</a>.</p><nav class=language-switcher><strong>Adapt for:</strong><ul><li data-type=language-java class=active>Java SDK</li></ul></nav><h2 id=using-joins>Using Joins</h2><p>Beam supports equijoins on schema <code>PCollections</code> of Schemas where the join condition depends on the equality of a subset of fields.</p><p>Consider using <a href=https://beam.apache.org [...]
