Jerry Cwiklik commented on UIMA-2180:
-------------------------------------
Extended UIMA AS client API to include
public String sendAndReceiveCAS(CAS aCAS,
List<AnalysisEnginePerformanceMetrics> componentMetricsList) throws
ResourceProcessException;
to provide application with per AE performance breakdown.
> UIMA AS primitive service should return performance breakdown for each CAS

> URL: https://issues.apache.org/jira/browse/UIMA-2180
> Project: UIMA
> Issue Type: New Feature
> Components: Async Scaleout
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.4.0AS
>
>
> Current UIMA AS code doesnt extract CAS per component performance breakdown
> from UIMA aggregate. Such breakdown would be very useful in identifying
> bottlenecks in a pipeline. This breakdown is available via AnalysisEngine's
> getManagementInterface(). The API accesses the same performance stats that AE
> exposes via JMX. Since these stats are cumulative, the UIMA AS code should
> calculate delta to obtain per CAS performance breakdown. Before calling
> processAndOutputNewCASes(), the code should make a copy (actually a deep
> copy) of AnalysisEngineManagement instance(s) and calculate delta (of
> analysisTime) before returning input CAS.
> The list containing the breakdown should be serialized into a reply message
> and de-serialized by the client. The UIMA AS client will provide an
> application the breakdown as a List via a callback method on
> UimaAsBaseCallbackListener.
