Hi Ivan - community guy here,
The AMQP Protocol does not specify such capabilities and I am pretty such Rabbit itself also does not. Essentially what the SpringBoot code is doing is simply stopping consuming the queue but not "pausing" in the meaning that, it has consumers registered and is not delivering messages.
From what you described in StackOverflow, if you wanted to mimic the behavior of SpringBoot (i.e removing a consumer) the RabbitMQ UI doesn't have that support (at - least, AFAIR???)
