Hi Esteban, A lot depends on a lot of things: 1) How much volume(total documents) 2) size of index 3) How you represent the data-aggregated part in your UI.
Your option-2 seems to be a suitable way to go. This way you tune each cores separately. Also the use-cases for updating each document/product in both indexes also seems different. One is updated when a product is added/updated. Other is updated when a product in viewed/sold from search results Option-1 can be used in case you are showing the data-aggregation stats on the search results page only along with each item. If it is shown in the item-detail page then option-1 seems better.
