/**
 * This annotation is used to mark entity classes or methods as indexed. Classes
 * or methods marked as @Indexed should always cache method values, even if
 * method value caching is turned off.
 * 
 * IMPORTANT: If you use this annotation in an application that uses the
 * CacheMessageManager to distribute cache updates to other instances, it is
 * your responsibility to ensure that your corresponding EntityGroup
 * ("distribute" defaulting to false) or CacheGroup ("distribute" defaulting to
 * true) has the "distribute" flag set to true. Otherwise each instance will
 * risk having a stale method value cache and you'll get wrong answers from
 * EntityStore.get() and list() and honestly it won't be very fun.
