+Hibernate Reactive supports having named data sources

+[source,properties]
+.Example `{config-file}`
+----
+# datasource configuration
+quarkus.hibernate-orm.datasource = named-datasource
+quarkus.datasource."named-datasource".db-kind" = postgresql
+
+# drop and create the database at startup (use `update` to only update the schema)

+%prod.quarkus.datasource."named-datasource".username" = quarkus_test
+%prod.quarkus.datasource."named-datasource".password" = quarkus_test
+%prod.quarkus.datasource.reactive.url = vertx-reactive:postgresql://localhost/quarkus_test <1>
+----

+When using a named data source, you need to set the `quarkus.hibernate-orm.datasource` property to the name of the data source.
