Tip If you specify a preprocessor, you generally also also specify worker thread settings, because event preprocessors are multithreaded (unless Caller’s Thread threading model is used, which is single threaded). Shared Queue Uses the TIBCO BusinessEvents system-wide shared queue and threads. For queue size and number of threads settings, see CDD Agent Classes Tab Settings Reference.Caller’s Thread Uses the thread (and queue size) provided by the channel resource client. There is one thread per destination.Note If it is important to ensure that acknowledgements are sent in the expected order with Caller’s Thread threading model, do not use the parallel operations option. See Agent.agentClassName.enableParallelOps in Table 57, CDD Agent Classes Tab Inference Agent and Query Agent Properties (Sheet 1 of 5).Destination Queue 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 Chapter 10, Threading Models and Tuning, in TIBCO BusinessEvents Architect’s Guide.
