[Erik Salter (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12603982#comment-12603982 ] 

Erik Salter commented on ISPN-312:
----------------------------------

Here's what I mean.

{code}
Group class InternalResourceKey { 

   String group;
   ... 
   @Group
   String getGroup() {
      return group;
   }
 }
{code}


{code}

InternalResourceKey key = new InternalResourceKey(); 

...
resourceCache.lock( key );

// Get the previous result.
ResourceResult result = resourceCache.get( key );

ResourceResult newResult = doWork( key, result );
resourceCache.put( key, newResult );

// I also want to group an external identifier that an external client knows about with the result so they will be on the same node
employeeCache.put( "111-111-1111", newResult, key.getGroup() );
{code}

>          Components: Core API, Distributed Cache, Eviction, Locking and Concurrency
>    Affects Versions: 4.0.0.Final, 4.1.0.Final
>            Reporter: Mindaugas Žakšauskas
>            Assignee: Pete Muir
>            Priority: Minor

>
> This is a spin-off from http://lists.jboss.org/pipermail/infinispan-dev/2009-December/001968.html.
> The requested feature would allow distinct entries to be assigned to custom arbitrary groups. Later in time those groups could be flushed on demand without any knowledge of entry keys.
> This feature exists in other open source cache library, see: http://www.opensymphony.com/oscache/api/com/opensymphony/oscache/base/Cache.html
