--------------------------------------
Summary: Provide scheduler calls to subscribe to additional roles
and unsubscribe from roles.
Key: MESOS-7258
URL: https://issues.apache.org/jira/browse/MESOS-7258
Project: Mesos
Issue Type: Improvement
Components: master, scheduler api
Reporter: Benjamin Mahler
The current support for schedulers to subscribe to additional roles or
unsubscribe from some of their roles requires that the scheduler obtain a new
subscription with the master which invalidates the event stream.
A more lightweight mechanism would be to provide calls for the scheduler to
subscribe to additional roles or unsubscribe from some roles such that the
existing event stream remains open and offers to the new roles arrive on the
existing event stream. E.g.
SUBSCRIBE_TO_ROLE
UNSUBSCRIBE_FROM_ROLE
One open question pertains to the terminology here, whether we would want to
avoid using "subscribe" in this context. An alternative would be:
UPDATE_FRAMEWORK_INFO
Which provides a generic mechanism for a framework to perform framework info
updates without obtaining a new event stream.
