             Summary: Introduce new web session granularity for consistent fine granularity replication
                 Key: WFLY-7119
                 URL: https://issues.jboss.org/browse/WFLY-7119
             Project: WildFly
          Issue Type: Feature Request
          Components: Clustering
    Affects Versions: 10.1.0.Final
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro
             Fix For: 11.0.0.Alpha1


Currently, ATTRIBUTE granularity sessions are vulnerable to partial stale reads, where some session attributes might have current data, and some are stale.  For some use cases, this might be intolerable.  For these use cases, we should introduce a new session granularity that tracks a version or checksum per attribute, that we can use to detect stale attribute cache entries.
This new granularity would retain the performance benefits of ATTRIBUTE granularity replication while maintaining the attribute consistency guarantees of SESSION granularity replication.
