....have more sophisticated trigger conditions sharing only partial indexable selection predicates. One idea is to choose the most selective conjunct for indexing, which is the topic of the next section. Due to the space limitation of the RPE paper, readers may refer to a longer version of this paper [18] for details. 4 Event Notification in JCQ Event notification is a software facility that provides mechanisms for notification of event occurrences. Generally speaking, an Event Notification Service (ENS) protocol will have minimum and maximum latency bounds on both event observation and update ....
....the loosely coupled notification service, a tightly coupled one has the advantage of less network communication overhead, but it loses some flexibility and harder to be implemented generically. Due to the space limitation of the RPE paper, readers may refer to a longer version of this paper [18] for details. 4.2 Discussion Latency is an important factor in the JCQ notification service. The source observer (whether it is sourceinitiated or polling based) sets the sampling latency, bounding the delay from source event occurrence until observation. We refer to such delay as the ....
