public class PeriodicDeltaChangeListener
A "simple" implementation that periodically persists all entities/locations/policies that have changed
since the last periodic persistence.
TODO A better implementation would look at a per-entity basis. When the entity was modified, then
schedule a write for that entity in X milliseconds time (if not already scheduled). That would
prevent hammering the persister when a bunch of entity attributes change (e.g. when the entity
has just polled over JMX/http/etc). Such a scheduled-write approach would be similar to the
Nagle buffering algorithm in TCP (see tcp_nodelay).
