+    #  * Schema: Choose one slice in a replica.
+    #    Because all slices has the same schema.
+    #    (Should we add "select" type to Dataset#copmute_routes for the case?)
+    #  * Fact table: Choose all slices in a replica.
+    #    Because records for the fact table are distributed in all slices.
+    #    (Should we add "gather" type to Dataset#copmute_routes for the case?)
+    #  * Other tables: Choose one slice in a replica.
+    #    Because all slices has all records for other tables.
