LiveFieldValues

abstract class LiveFieldValues<S, T : Any>(mgr: ReferenceManager<S>, missingValue: T) : ReferenceManager.RefreshListener, AutoCloseable

Tracks live field values across NRT reader reopens. This holds a map for all updated ids since the last reader reopen. Once the NRT reader is reopened, it prunes the map. This means you must reopen your NRT reader periodically otherwise the RAM consumption of this class will grow unbounded!

NOTE: you must ensure the same id is never updated at the same time by two threads, because in this case you cannot in general know which thread "won".
