I am always torn between the "convention" we have and the better way of doing things. But I don't have strong opinions about it. I can change it. > One more suggestion is to have a static factory method in the ProcessorIdGenerator (Like what we have in ApplicationRunner): I couldn't grasp these requirements from the ApplicationRunner design. It will be great if you can put it out in an SEP :) I can add the static factory method for it. Just to clarify, the static method simply class loads the ProcessorIdGenerator ? It uses reflection to create the instance ? Thanks! Navina On Thu, Mar 16, 2017 at 4:31 PM, xinyu liu <xinyuliu...@gmail.com> wrote: > The proposal looks great to me!
