Jeff DeLong commented on RTGOV-393:
-----------------------------------
It should be configurable, STREAM vs CLOUD. Stream has many advantages for CEP scenarios
but has a cost. We could discuss which is the best default for rtgov. There are strategies
from dealing with fault tolerance of CEP applications; rtgov is no different in this
regard. In most scenarios I would recommend a single RTGov server with multiple
SwitchYard servers with rtgov client (we plan to demonstrate this topology in our
reference architecture as well). For most scenarios I think this is sufficient, that is
failure of the rtgov service would be temporary and not core to the primary business
process.
DroolsEventProcessor. Support Drools STREAM and CLOUD event
processing
----------------------------------------------------------------------
Key: RTGOV-393
URL: https://issues.jboss.org/browse/RTGOV-393
Project: RTGov (Run Time Governance)
Issue Type: Feature Request
Components: Event Processor
Reporter: ivan mckinley
Assignee: Gary Brown
Fix For: 2.1.0.Final
When attempting to using sliding window rules, see[1]. Results in a runtime exception as
the DroolsEventprocessor does not support a Stream of events.
Recommend fix is making the DroolsEventprocessor configurable from the EPN to use either
stream or cloud.
http://docs.jboss.org/jbpm/v6.0.1/javadocs/org/kie/api/builder/model/KieB...
Browsing through the history shows this functionality was removed.
