[rabbitmq-discuss] Shovel with exchange-exchange bindings

[Busoli, Simone]

I'm trying to set up a shovel with exchange-exchange bindings to workaround the issue with infinite loops when configuring a symmetric shovel between two brokers (to achieve transparent bidirectional communication), but I get an error on broker startup as if the shovel didn't support exchange-exchange bindings.

As suggested by Matthew some time ago on the list this is what I'm trying to accomplish:

              /---------------------[ Shovel 2 ]---------------------\
              |                                                      |
              V                                                      |
--->[X1]--->[X2]---->[[my queues]]        [[my queues]]<---[X2]<---[X1]<---
     |                                                       ^
     |                                                       |
     \------------------[ Shovel 1 ]-------------------------/


But on broker startup I get  this:

{"Kernel pid terminated",application_controller,"{application_start_failure,rabbitmq_shovel,{{invalid_shovel_configuration,test1,{invalid_parameter_value,sources,{unknown_method_name,'exchange.bind'}}},{rabbit_shovel,start,[normal,[]]}}}"}

Here is the configuration fragment:

{test1,
      [{sources, [{broker, "amqp://"},
                       {declarations,
                          [	{'exchange.declare',
                                  [{exchange, <<"X1">>},
                                   {type, <<"topic">>}]},
		{'exchange.declare',
                                  [{exchange, <<"X2">>},
                                   {type, <<"topic">>}]},
		{'queue.declare',
		   [{queue, <<"xshovelqueue">>}]},
                           {	'queue.bind',
                                  [{exchange, <<"X1">>},
                                   {queue,    <<"xshovelqueue">>},
		   {routing_key, <<"#">>}]},
		{'exchange.bind',
                                  [{source, <<"X1">>},
                                   {destination,    <<"X2">>},
		    {routing_key, <<"#">>}]}
                          ]}]},
       {destinations, [{broker, "amqp://localhost/shovel"},
                       {declarations,
                          [{'exchange.declare',
                                  [{exchange, <<"X2">>},
                                   {type, <<"topic">>}]}
                          ]}]},
       {queue, <<"xshovelqueue">>},
       {auto_ack, false},
       {tx_size, 0}
      ]}
