[infinispan-issues] [JBoss JIRA] (ISPN-694) Create expiration notification for in-memory cache entries

[Mircea Markus (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12956747#comment-12956747 ] 

Mircea Markus commented on ISPN-694:
------------------------------------

Here's a concern I have for entries written with maxIdle. owners(k) = {N1, N2}
- if entry is read on N1 repeatedly, and never on N2. then N2 will deceide that maxIdle time has passed and remove the entry
- this will never happen on N1, as max might never be reached
Also a notification will only be triggered on N2, and not on N1. 
I guess people using maxIdle don't have high consistency guarantees, but this behavior is pretty awkward and should be documented accordingly. 
I would also be curious to hear [~william.burns] thoughts on whether this functionality can be exposed over clustered listeners (and then remote listeners).

> 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.
