I have never had a good experience with RabbitMQ wherever I have worked. Often it was buggy and unreliable. It’s almost always been some thing shoehorned into a service, but failed to gain widespread adoption with future services. Furthermore, it’s usually some hot potato no one even wants to deal with. We have written some code around it to make it more reliable. You quickly figure out why there seems to be so many half baked implementations of it wherever you go work.

It’s basically caught between being too bloated and complex for use with smaller systems (as some commenters have poked at people for not being the ‘right’ kind of person to be running it)

While at the same time, it’s not robust and reliable enough to use in prime time.

What’s left is this enticing and sexy sounding message broker called RabbitMQ that actually just sort of sucks.

In my experience someone gets stoked on trying this out but once everything is all implemented it disappoints and the system or service it is apart of is a one off after future services use something more mature the next time around.

For scale I have used NSQ to handle millions of message a second and then for smaller scale AWS services like SQS can handle things much more reliably.
