Subject [jira] [Created] (QUARKS-147) adaptable TWindow width
Date Mon, 18 Apr 2016 20:07:25 GMT
Dale LaBossiere created QUARKS-147:
--------------------------------------

             Summary: adaptable TWindow width
                 Key: QUARKS-147
                 URL: https://issues.apache.org/jira/browse/QUARKS-147
             Project: Quarks
          Issue Type: Improvement
          Components: Runtime
            Reporter: Dale LaBossiere


Just like there's a need for adaptable Topology.poll() behavior (QUARKS-131), applications
will need the ability to adapt a window's width as demanded by conditions.

e.g., maybe a condition occurs that motivates increasing the window width to improve the accuracy
of an analytic.  Or maybe the app decides that it should reduce the width as a result of processing
time or memory pressure concerns.

Notes:
- add TWindow.alias(), getAlias()
- time based window would register and handle PeriodicMXBean
- count based window would register and handle a new MBean - e.g., CountMXBean ?
