With the release of 2018.3, cache has become an adhoc task. With complex workflow and multiple inputs we need a method to cache and save the cache selection by tool. Once the workflow runs after opening, the cache would be saved at the latest tool downstream.
This way we don't have to create adhoc cache steps and run the workflow 2X before realizing the time saving features of cache.
This would work similar to the cache feature in 11.0 but with enhanced functionality...the best of the old cache with the new cache intent.
