[rabbitmq-discuss] upgrading message consumers

[Petar Shomov]

Hi guys,

I have a message that takes relatively long to process. I have a few 
instances of this message consumer running and processing messages. Next I 
have a new version of the consumer that I would like to deploy. I would like 
to upgrade the consumers (one by one or all at the same time, not a big 
difference to me) without crashing whatever they might be doing at the 
moment. Are there any best practices around this process?

I was thinking about writing a file in a well known location which each 
consumers will check for after they are done processing a message and before 
they accept the next one. Something along those lines.

Any ideas are welcome!

Regards,

Petar
