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

                 Key: ISPN-748
                 URL: https://jira.jboss.org/browse/ISPN-748
             Project: Infinispan
          Issue Type: Feature Request
          Components: Core API
            Reporter: Sanne Grinovero
            Assignee: Manik Surtani
            Priority: Minor
             Fix For: 5.0.0.BETA1, 5.0.0.Final


On mailing list we discussed the possibility to provide the same methods as defined by Map but omitting return values.

This would be useful for those cases in which return values are not needed, so that Infinispan can enable all possible optimizations to disregard retrieveing an appropriate return value.
Several alternatives where proposed, and there's also an interesting proposal to do the same relating to async methods, and the combination of async+noReturn

A suggestion:

cache.noReturnValue().remote(K); //returns void and enables both flags SKIP_CACHE_LOAD and SKIP_REMOTE_LOOKUP.

The advantage is that people refactoring code don't have to remember to adjust flags according to using the return value or not, or would at least get a compiler error in case of abuse of method; also Infinispan might introduce more optimizations in future and apply them without code changes for new flags arising.
