             Summary: Invalidation commands should not load the previous value from the store
                 Key: ISPN-11118
                 URL: https://issues.redhat.com/browse/ISPN-11118
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 9.3.6.Final, 9.4.17.Final, 10.0.1.Final, 10.1.0.Final
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 11.0.0.Final, 10.1.1.Final


{{CacheLoaderInterceptor.visitInvalidateCommand()}} loads the previous value from the store, just in case there is a {{CacheEntryInvalidated}} listener that needs the previous value. This makes invalidation mode with a shared store very costly: for every write, every node receives an invalidation command, every node reads the value from the store, and then discards it.

But {{InvalidateCommand}} only removes entries from memory, it never removes entry from stores (either shared or private). If we don't load the previous value in the data container, there is nothing for the {{InvalidateCommand}} to do. No invalidated entry means no listener notifications, so we don't need to load the previous value or to change the behaviour of {{CacheEntryInvalidatedEvent}}.
