Yep, I actually have the same question at the same time haha ( How to Populate Celery Cache in Background - Dash Python - Plotly Community Forum). Would love if @adamschroeder might be able to weigh in and help us out? I think I’d get pretty heavy usage out of this functionality, so seems worthwhile to grab a good example or explanation before forging out on my own with this one.
Edit: Might be an example worthwhile adding to the docs under the Background callback caching section.
