An international merchant is complaining that changes are taking too long to be reflected on the frontend after a full product import.
Thinking it may be database issues, the Adobe Commerce developer collects the following entity counts:

Categories: 900 -

Products: 300k -

Customers: 700k -

Customer groups: 106 -

Orders: 1600k -

Invoices: 500k -

Creditmemos: 50k -

Websites: 15 -

Stores: 45 -
What is a probable cause for this?

A The combination of the number of products, categories and stores is too big. This leads to a huge amount of values being stored in the flat catalog indexes which are too large to be processed at a normal speed.
B The combination of the number of orders, customers, invoices and creditmemos is too big. This leads to a huge amount of values being stored in the customer grid index which is too large to be processed at a normal speed.
C The combination of the number of products, customer groups and websites are too big. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed.
