Amazon MQ now supports the ability for customers to create and apply configurations to their RabbitMQ broker on Amazon MQ. This feature allows you to define the RabbitMQ delivery acknowledgement timeout (consumer_timeout) value and enable operator policies using the RabbitMQ configuration format (Cuttlefish). You can now exert greater control over your RabbitMQ broker and fine tune the performance of your consumer applications or enable and manage high availability operator policies directly through configuration.
