Question 74

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 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.

B.The combination of the number of products, customer groups and websites is 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.

C.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.
