[Manik Surtani (JIRA)]

    [ https://jira.jboss.org/browse/ISPN-694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12558459#action_12558459 ] 

Manik Surtani commented on ISPN-694:
------------------------------------

@Trustin I would then defer this task.  Getting a cache store to return the entries purged is very expensive in some cases (e.g., the CloudCacheStore) which will result in remote calls to a cloud storage provider for each entry, plus deserialization, etc etc.  So in general, -1 for this notification to be emitted via CacheStore.purgeExpired().  But that leaves us with incomplete/inconsistent notifications for expired entries.  So again, -1 to this feature request/patch for now ... at least until there is a more workable solution proposed.

> Create a CacheEntryExpired notification and make EvictionManager send this notification when a cache entry is evicted because it is expired.
> Also mage sure the cache entry value is sent over in the event.
> CacheEntryEvicted notification should also send the entry value in the event.
