4.6.2. Declaring a Last Value Queue
Last Value Queues are created by supplying a
qpid.last_value_queue_key when creating the queue.
For example, to create a last value queue called
stock-ticker that uses stock-symbol as the key, using qpid-config:
qpid-config add queue stock-ticker --argument qpid.last_value_queue_key=stock-symbol
To create the same queue in an application:
- Python
myLastValueQueue = mySession.sender("stock-ticker;{create:always, node:{type:queue, x-declare:{arguments:{'qpid.last_value_queue_key': 'stock-symbol'}}}}")
Both string and integer values can be provide as the last value. Using the example queue created above, valid values for the stock-symbol key would include "
RHT", "JAVA", and other string values; and also 3, 15, and other integer values.
