Starting with Magento 2.3.0, the Magento_Queue module for RabbitMQ becomes part of the Open Source edition.

But I cannot find documentation on how it's being used in the core. Are there already features in the Open Source version, formerly known as Community Edition, that use RabbitMQ, if configured? Which ones?
