Cluster Deployment Descriptor Reference : Collections Tab — Destinations Settings and Properties

Collections Tab — Destinations Settings and Properties
Also available from the Agent Classes Tab.
When you select a destination in the CDD editor, you add deploytime settings and properties as needed (shown below). Doing so creates a destination configuration. Each destination configuration is assigned a unique ID. You can select and configure a destination in two places in the CDD: in the Collections tab, or in the Agent Classes tab.
Uniquely identifies this destination configuration at runtime. Edit as needed to ensure that each destination in the cluster has a unique deployment name.
Shared Queue  Uses the TIBCO BusinessEvents system-wide shared queue and threads. See Properties for Shared Queue and Threads Threading Model.
Caller  Uses the thread (and queue size) provided by the channel resource client. There is one thread per destination.
Workers  TIBCO BusinessEvents creates a dedicated thread pool and set of worker threads in each destination. See Thread Count and Queue Size below.
For more information on threading models see TIBCO BusinessEvents Architect’s Guide.
