What is the mechanism through which nameko can connect to multiple rabbitmq host configured in mirrored mode so that HA can be achieved using it.

Most people put a load-balancer in front of the RabbitMQ nodes. Another approach is to pass a semicolon delimited string with the addresses of each node as the AMQP_URI, e.g.
AMQP_URI: pyamqp://guest:guest@rabbitmq1:5672/;pyamqp://guest:guest@rabbitmq2:5672/
This passes through to Kombu, which will round-robin between URIs when it can’t connect.
HA strategies in general have been covered on the mailing list: https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!searchin/nameko-dev/HA|sort:date/nameko-dev/DpR8LeNUod0/uOethL81AgAJ
This doesn’t seem to work anymore :-/
I have 4 Rabbit servers with 2 offline, and none of the workers are falling back to the online servers.
