Summary: need easy way to get PeriodicMXBean associated with a
poll() invocation
Key: QUARKS-131
URL: https://issues.apache.org/jira/browse/QUARKS-131
Project: Quarks
Issue Type: Improvement
Reporter: Dale LaBossiere
Assignee: Dale LaBossiere
I think we're missing some API is missing to make this all usable.
A Topology/TStream domain user needs an easy way to get the PeriodicMXBean for
a particular Topology.poll() invocation.
The PeriodicSource oplet implements PeriodicMXBean which allows changing the
period.
The only demonstrated use is by DirectJobTest.jobPeriodicSourceCancellation(),
which iterates over the Topology's underlying graph for instanceof
PeriodicSource oplet (it's the only ProcessSource oplet in the graph for this
test).
That's certainly not easy / convenient / nor in the "TStream" domain the user
is mostly operating in.
[~djd] [~vdogaru] what schemes for addressing this have already been considered
/ decided? Some sort of "control bean registry service" where a user gets to
supply a name (e.g., to poll()) and the runtime registers the bean (e.g.,
PeriodicMXBean) under that name? If there's not a concrete plan lets work on
that here.
