1. What is UIMA-AS?

UIMA Asynchronous Scaleout (AS) is an add-on to Apache UIMA that provides a set of capabilities for achieving flexible scaleout. It is a second generation design, replacing the CPM and Vinci Services. The CPM and Vinci are still available and are not being deprecated, but new designs are encouraged to use UIMA-AS for scalability, and current designs reaching limitations may want to move to UIMA-AS.

UIMA-AS is integrated with the new flow controller architecture, and can be applied to both primitive and aggregate analysis engines. It fully supports CAS Multipliers.
