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.
