Hey all, what is the best practice for setting variables on the job itself, for example, if I wanted to set the value for "environment" and have it retrievable from any op what would be the best way? Currently, I am just setting it on the ops that need it via config, however, for bigger jobs I could see this being tedious. Also don't want to set it via environment variable because I want it more as a configurable option than something you have to set outside of dagster itself.
