Should I gracefully close rabbitmq client application ?

[Yury Kozlov]

According to the docs:

 When an application no longer needs to be connected to the server, it should gracefully close its AMQP 0-9-1 connection instead of abruptly closing the underlying TCP connection.

https://www.rabbitmq.com/tutorials/amqp-concepts.html#amqp-connections

However when I terminate a golang process with few consumers I immediately see on rabbitmq management that connection automatically disappears and all underlying channels are also closed. Meaning that the broker is able to handle abruptly closed connections.

I wonder if explicitly closing client connections (on SIGTERM, SIGKILL, etc) is mandatory? 

What are possible consequences of abruptly closed clients?

Thanks in advance.

Just to recap, as per  Connection lifecycle events:  Abruptly closed connections can be harmless.
