Configuring the storage of events for aggregation nodes
You can use an Aggregation configurable service to control the storage of events for AggregateControl and AggregateReply nodes.
By default, the storage queues used
by all aggregation nodes are:
- SYSTEM.BROKER.AGGR.CONTROL
- SYSTEM.BROKER.AGGR.REPLY
- SYSTEM.BROKER.AGGR.REQUEST
- SYSTEM.BROKER.AGGR.UNKNOWN
- SYSTEM.BROKER.AGGR.TIMEOUT
However, you can control the queues that are used by different aggregation nodes by creating alternative queues containing a QueuePrefix, and using an Aggregation configurable service to specify the names of those queues for storing events.
Follow these steps to specify the queues that are used to store event states, and to set the expiry time of an aggregation:
The properties for the configurable service are not used
by the broker until you restart or redeploy the message flow, or restart
the broker.
