+@url{https://www.rabbitmq.com/streams.html, RabbitMQ Streams} using
+@url{https://docs.python.org/3/library/asyncio.html, @code{asyncio}}.
+
+It is designed and implemented with the following qualities in mind:
+@itemize
+@item asynchronous Pythonic API with type annotations
+@item use of
+@url{https://en.wikipedia.org/wiki/Advanced_Message_Queuing_Protocol, AMQP}
+1.0 message format to enable interoperability between RabbitMQ Stream. clients
+@item auto reconnection to RabbitMQ broker with lazily created connection
+objects
+@end itemize
+
+Support of many RabbitMQ Streams broker features:
+@itemize
+@item publishing single messages, or in batches, with confirmation
+@item subscribing to a stream at a specific point in time, from a specific
+offset, or using offset reference
+@item stream message filtering
+@item writing stream offset reference
+@item message deduplication
+@item integration with AMQP 1.0 ecosystem at message format level
+@end itemize")
