LVQ on linked queue

[joseluis <jl...@gmail.com>]

Is it possible to configure the linked queue of a topic to work with LVQ?



I'm using an exchange with a linked queue with this configuration


testing/#; 
{ 
  assert: allways, 
  node : 
  { 
    type: topic 
  }, 
  link: 
  { 
    durable: false, 
    x-declare: 
    { 
      auto-delete: true, 
      exclusive: True, 
      arguments: 
      { 
        'qpid.max_count': 1000000, 
        'qpid.max_size': 10000000, 
        'qpid.policy_type': ring 
      } 
    } 
  } 
} 


kind regards

Yes, although an LVQ with browsers also behaves much like a topic.

For an LVQ you want to add an argument here:

'qpid.last_value_queue_key': 'xyz'

where xyz is the name of the property on which you want the LVQ to be keyed.
