-----------------------------------
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.
