+Substrait
+=========
+
+The ``arrow-dataset`` module can execute Substrait_ plans via the :doc:`Acero <../cpp/streaming_execution>`
+query engine.
+
+Executing Substrait Plans
+=========================
+
+Plans can reference data in files via URIs, or "named tables" that must be provided along with the plan.
+
+Here is an example of a Java program that queries a Parquet file using Java Substrait
+(this example use `Substrait Java`_ project to compile a SQL query to a Substrait plan):
