-----------------------------------

             Summary: Null value read with RR can be replaced by cache loader value
                 Key: ISPN-3829
                 URL: https://issues.jboss.org/browse/ISPN-3829
             Project: Infinispan
          Issue Type: Bug
          Components: Loaders and Stores
    Affects Versions: 6.0.0.Final
            Reporter: William Burns
            Assignee: Mircea Markus


Currently the CacheLoaderInterceptor does the following check to determine if it should check the loader for a value

{code}
if (e == null || e.isNull() || e.getValue() == null) {
{code}

Unfortunately this means it checks the loader when a null value is in the entry when using RR.  This can cause an issue if another transaction commits that key and puts a value that results in that value being inserted into the loader.

This also is a performance issue for RR, since it has to check the loader over and over for a given key even if it was found null the first time.

Initial thought is to do something like setSkipRemoteGet and that could actually be used for a dual purpose possibly.
