[rabbitmq-discuss] active-active implementation in php

[Robin Harvey]

Alvaro - does php-amqplib support incoming consumer cancels?


Out of interest, how does the client know where to re-connect to when a
queue fails (i.e. which slave got promoted)?  I've seen the following
(here: http://www.rabbitmq.com/ha.html):

> Clients that were consuming from the mirrored-queue and support our Consumer
Cancellation Notifications<http://www.rabbitmq.com/extensions.html#consumer-cancel-notify>extension
will receive a notification that their subscription to the
mirrored-queue has been abruptly cancelled. At this point they should
re-consume from the queue, which will pick up the new master

...but this doesn't give much detail.  Are the reconnection parameters in
the consumer.cancel method?


Thanks,
--Robin
