Having interfaces for a Parameter Server service in Flink is a very good
idea, IMO. This interface can be implemented for different backends, such as
Ignite or an own lightweight implementation.
However, I doubt that it really necessary to bake the Parameter Server
master into the JobManager. Can't this be a completely stand-alone service to
which Flink programs write to and read from via the provided interfaces?
