[infinispan-issues] [JBoss JIRA] (ISPN-8331) CacheEntryExpiredEvent.getValue() is always null when entry expired from cache store

[William Burns (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-8331?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

William Burns updated ISPN-8331:
--------------------------------
    Issue Type: Enhancement  (was: Bug)


Unfortunately this is the way the loader spi was implemented. I would love to change this to support values as well. If we do, we may want to provide a way to optionally pull the value such as a `Supplier` to get the value. I am not sure if we have implementations that it may be very costly to pull the value or not.

Also cc/ [~ryanemerson] since he has been dealing with loaders recently.

> AdvancedCacheWriter.PurgeListener callback only sends the key of the expired entry.
> Proposal:
> AdvancedCacheWriter.PurgeListener.entryPurged(MarshalledEntry entry);
> This way, we only incur the cost of unmarshalling value/metadata when requested.
