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: 12.0.0.Final 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.
