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

             Summary: SingleFileStore can run process method substantially faster when it doesn't require values or metadata
                 Key: ISPN-8924
                 URL: https://issues.jboss.org/browse/ISPN-8924
             Project: Infinispan
          Issue Type: Enhancement
          Components: Loaders and Stores
            Reporter: William Burns
            Assignee: William Burns
             Fix For: 9.2.1.Final, 9.3.0.Alpha1


The SingleFileStore always reads from the file. However if value and metadata are both not needed, there is no reason to go to the file. Instead we can just check the expiration on the file entry and return the keys immediately.

This along with ISPN-8923 will provide a SUBSTANTIAL boost for keySet iteration methods when using SingleFileStore.
