[rabbitmq-discuss] How to deal with duplicated msgs when using HA mirror?

[黄大鹏]

Hi all,

As the article <<High Availability in RabbitMQ: solving part of the
puzzle<http://www.rabbitmq.com/blog/2011/10/25/high-availability-in-rabbitmq-solving-part-of-the-puzzle/>>>
mentioned, when master breakdown,  the last ack maybe not sync to all
slave,so when a slave promote to be a new master, the msgs which actualy be
consumed maybe redelivered to the consumers.
Is there any way to  identify these duplicated messages? our  scenario is :
multi producers, multi queue (every consumer has a private queue ), a
direct exchange and a fanout exchange.

Thanks
