When non-persistent monitors are useful
A correlator that is running with persistence enabled can have persistent and non-persistent monitors injected. Non-persistence is a good choice for a monitor that does one or more of the following:
Interacts with user-defined EPL plug-ins or Apama EPL plug-ins other than the Time Format or MemoryStore plug-ins.
Contains large amounts of fast-changing state that is undesirable to persist for performance reasons.
Operates as a stateless utility that just responds to incoming events.
Contains minimal state that can be reconstructed by the
onBeginRecovery() action on a persistent monitor.
