Persistant cache we use when our data or lookup values are not changing frequently so as we know Persistant cache will be saved in cache folder so it can be reused in next session run. Because of this reusability this will basically reduce the run time of workflow.

Also since in persistant cache we have a copy of cache file we can share the same cache to other session if it required.

I want my deployment group to refer an external configuration file, while i deploy in the production environment. How can i achieve it.
