 From the application code point of view, using a super stream is mostly configuration-based.
 Some logic must also be provided to extract routing information from messages.

+==== Super Stream Creation and Deletion
 
-It is possible to create the topology of a super stream with any AMQP 0.9.1 library or with the https://www.rabbitmq.com/management.html[management plugin], but the `rabbitmq-streams add_super_stream` command is a handy shortcut.
-Here is how to create an invoices super stream with 3 partitions:

+* any AMQP 0.9.1 client library
+* the https://www.rabbitmq.com/management.html[management plugin]
+
+The stream Java client and the dedicated CLI commands are easier to use as they take care of the topology details (exchange, streams, and bindings).

+
+The super stream partitions will be `invoices-0`, `invoices-1`, ..., `invoices-5`.
+We use this kind of topology when routing keys of outbound messages are hashed to pick the partition to publish them to.
+This way, if the routing key is the customer ID of the invoice, all the invoices for a given customer end up in the same partition, and they can be processed in the publishing order.

+It is also possible to specify binding keys when creating a super stream:
