AsyncToSyncCacheAdapter

trait AsyncToSyncCacheAdapter[K, V] extends SyncCache[K, V] with SyncCacheEventNotifierImpl[K, V] with AsyncCacheEventHandler[K, V] with DerivedCacheBaseImpl

Adapts an AsyncCache to the SyncCache interface. Updates to the async parent cache become visible as the values become available and cache lookups to the sync cache trigger async on-cache-miss. But due to the sync nature of the adapter, these cache misses only become visible when the async call has returned, i.e. some time later. The behaviour will be that a cache miss will return None initially and Some some time later.
