             Summary: Improve concurrency of requests for the same session when using distributed web sessions
                 Key: WFLY-4650
                 URL: https://issues.jboss.org/browse/WFLY-4650
             Project: WildFly
          Issue Type: Enhancement
          Components: Clustering
    Affects Versions: 9.0.0.CR1
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro


Many people are encountering lock timeouts when using the asynchronous servlet API in concert with distributed web sessions.
Our default configuration (pessimistic, REPEATABLE_READ isolation) effectively serializes access to the session.
Currently, we require locking on every request, since all requests involve updating the last access timestamp of the session.  We should relax this constraint, such that only session attribute modifications require locking.
