+/**
+ * Load test for operations involving side inputs.
+ *
+ * <p>The purpose of this test is to measure cost of materialization or lookup of side inputs. It
+ * uses synthetic sources and {@link SyntheticStep} which can be parametrized to generate records
+ * with various sizes of keys and values, impose delays in the pipeline and simulate other
+ * performance challenges.
+ *
+ * <p>To run the test manually, use the following command:
+ *
+ * <pre>
+ * ./gradlew :sdks:java:testing:load-tests:run -PloadTest.args='
+ * --sourceOptions={"numRecords":2000, ...}
+ * --sideInputType=ITERABLE
+ * --accessPercentage=1
+ * --windowCount=200
+ * </pre>
