I dont need meta keys like downloadable or virtual and many more which are automatically gernated from woocommerce and stored in postmeta table. As i have over 2m affiliate products i think stopping this generation of unnessesary Meta keys would reduce the size of postmeta table and speed up product import. But i dont know where or how to delete the meta keys generation.
does anyone have a clue how to do it ?
Thanks a lot for help
