org.apache.uima.ducc.common.config.DuccBlastGuardPredicate
Ducc Predicate which should be placed in Camel timer routes to prevent blast of messages flooding DUCC daemons. Its been observed that these blasts occur although the exact reason is not yet understood. This predicate detects how much time passed since the last time the prodicate was called. If the interval is 1 sec or less, the guard returns false forcing the route to end and dispose current message.
