             Summary: Redesign UIMA-AS to simplify embedding in applications
                 Key: UIMA-5280
                 URL: https://issues.apache.org/jira/browse/UIMA-5280
             Project: UIMA
          Issue Type: Improvement
          Components: Async Scaleout
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 3.0.0AS


The current UIMA-AS runtime requires an ActiveMQ broker to be running to support message exchanges between an application and UIMA-AS based service. An application uses the UIMA-AS client API to send CASes to a service for analysis. A CAS is serialized by the client, wrapped in a Message object and delivered to a JMS queue. A service than dequeues the message and deserializes a CAS contained within it. Reverse happens on a reply. In total, such exchange requires two serializations and two deserializations of the CAS.

To avoid such overhead, a collocated service deployment in the new design will use java queues for transport and pass a CAS by reference.
