[openstack-dev] [taskflow] Recommendations for the granularity of tasks and their "stickiness" to workers

Folks,
A question for the taskflow ninjas.
Any thoughts on best practice WRT $subject?
Specifically I have in mind this ceilometer review[1] which adopts
the approach of using very fine-grained tasks (at the level of an
individual alarm evaluation) combined with short-term assignments
to individual workers.
But I'm also thinking of future potential usage of taskflow within
ceilometer, to support partitioning of work over a scaled-out array
of central agents.
Does taskflow also naturally support a model whereby more chunky
tasks (possibly including ongoing periodic work) are assigned to
workers in a stickier fashion, such that re-balancing of workload
can easily be triggered when a change is detected in the pool of
available workers?
Cheers,
Eoghan
