+/**
+ * A IO to publish or consume messages with a RabbitMQ broker.
+ *
+ * <h3>Consuming messages from RabbitMQ server</h3>
+ *
+ * <p>{@link RabbitMqIO} {@link Read} returns an unbounded {@link PCollection} containing RabbitMQ
+ * messages body (as {@code byte[]}).
+ *
+ * <p>To configure a RabbitMQ source, you have to provide a RabbitMQ {@code URI} to connect
+ * to a RabbitMQ broker. The following example illustrates various options for configuring the
+ * source:
+ *
+ * <pre>{@code
+ *
+ * pipeline.apply(
+ * RabbitMqIO.read().withUri("amqp://user:password@localhost:5672").withQueue("QUEUE")
+ *
+ * }</pre>
+ *
+ * <h3>Publishing messages to RabbitMQ server</h3>
+ *
+ * <p>{@link RabbitMqIO} {@link Write} can send {@code byte[]} to a RabbitMQ server queue.
+ *
+ * <p>As for the {@link Read}, the {@link Write} is configured with a RabbitMQ
+ * {@link ConnectionConfig}.
+ *
+ * <p>For instance:
+ *
+ * <pre>{@code
+ *
+ * pipeline
+ * .apply(...) // provide PCollection<byte[]>
+ * .apply(RabbitMqIO.write().withUri("amqp://user:password@localhost:5672").withQueue("QUEUE"));
+ *
+ * }</pre>
