How would one go about efficiently creating metafields for products in shops with 10s of thousands of products
I'm developing an app and to be efficient and reduce the amount of data pulled from my servers (better for page load speeds etc) I'd like to store some data in the metafields.
Those are quite cool but what if a shop has, say 50k products? If I use the API I will have to wait for my installation process to run multiple days! Is there any way to create those metafields in bulk? Or any other efficient way? I can't find anything in the API description.
