There is a new feature in rabbitmq 3.1.0 - eager synchronization.  
What is this eager synchronization in detail?  
Should I explicitly set eager sync policy?

With eager sync enabled, queues will block (i.e., become unresponsive) when a new mirror/slave joins, whilst the slave is synchronised.

It will only happen if you *do* explicitly set ha-sync-mode to automatic, or manually call 'sync' via rabbitmqctl.

Cheers,
