RFE: QMF Object publishing interval scoped to type
Last modified: 2013-02-26 16:21:10 EST
QMFv1 (and v2) as of 0.9.1079953-2, supports controlling the frequency at which an agent will broadcast updates to a broker (qpid::management::ManagementAgent::init(..., intervalSeconds, ...)). The frequency is scoped to the agent.
In a Grid deployment, a single agent will be publishing multiple types. For instance, the Schedd agent will publish classes Scheduler, Submitter, JobServer and Submission. See bug 689785.
Different types may have different freshness requirements. For instance, Submission data with an SLA of 15 seconds from condor_submit to visibility in Cumin, and Submitter data with a 30 second SLA.
Furthermore, in a scaled up system it becomes important to adjust the update intervals, often based on consumer performance.
The ability to specify the interval on a per class basis, at runtime, will satisfy this RFE.
