             Summary: Avoid creating MarshallableEntry instances if no CacheWriter enabled
                 Key: ISPN-9932
                 URL: https://issues.jboss.org/browse/ISPN-9932
             Project: Infinispan
          Issue Type: Enhancement
          Components: Loaders and Stores
    Affects Versions: 10.0.0.Alpha3
            Reporter: Ryan Emerson
            Assignee: Ryan Emerson
             Fix For: 10.0.0.Beta1


The (Dist)CacheWriterIntercepter is enabled if any loader/store is configured. The problem, is that the interceptor assumes that a CacheWriter is always configured.  However, it is possible that only a CacheLoader has been configured, in which case when a write command visits the interceptor, MarshallableEntry instances are created unnecessarily in order to call the various PersistenceManager write operations. 

To avoid unnecessary allocations and the marshalling of key/value/metadata that is never stored, we should ensure that calls to PersistenceManager write methods are only called if a CacheWriter is actually configured.
